I Might loose my girlfreind(very long sorry but plz read and answer)?

Ok so i am with a girl im 19 she is 17. so this last week my girlfreind has has to show a steer in the fair. this year was a big year for her, her parents put pressure to do good cuz she was the oldest in the house. so she has been really stressed. so everything started out just fine but by the end of the first day her mom was upset that we were being to affectionate the family is LDS but she doesnt care for she just does it cause she is living with them. so her mom got after her that about it and the next time i went to hug her she kept moving away and saying not to even when her mom wasnt around then she started ignoring me the next day was the same thing and i started to get kinda worried thinking something was wrong so that night i asked her if the next day if we could have some personal time for us she said yes that we could for sure have it. so the next day after i had helped my step dad with laying concrete for a garage he is building i went over to see her i called her and told her i was coming over and i asked if she was busy she said no i got over there and her dad came and asked her to do some stuff with the steers. so i helped her with that and after we did what she was asked we sat down and i asked if we could have our time she said in a min well for the next 6 hours it was the same thing. things would come up she couldnt do it. so she went home to change for a rodeo that night and she said while we were there we would for sure we got there she did all she had to do then said lets go i said what about our time? i had only asked her for 10 mins of time to be affectionate. well she said sorry i just dont have time we have to get back to the fair. i got upset cuz i had heard the same thing all day. i lost my temper and got mad about it. so we went back to the fair i left for home she called asked if i was gonna shower then come back, i was upset still so i said why should i so you can keep treating me like you have and she said that if i came back watched a showmanship round her brother was in afterwards we could go to my house and talk well the time came we went we talked she told me off about how i had be more annoying then anything over the week i told her my part of how i thought something was wrong and i was trying to fix it she said nothing was wrong until i started to act like i did. after more talking about it she had to go back for the rodeo. so the last day of the fair i expected things would be going back to normal she wouldnt be so stressed and such. so she couldnt have her phone for the first part of the day, her parents said she couldnt cuz she had to show her steer to sell. so i went watcher her show her steer to sell and i watched her brother and sister sell theirs. so it had rained the night before and with the freshly poured concrete wasnt good so i had to go and help make sure the concrete would be ok and i ended up tking a nap. i didnt have much sleep this week cause i had been upset and couldnt sleep. if fact that is why im writing this at 4 in the morning. so i woke up and soon after i had woke up my girlfreind called me we talked she said whe went home and naped to and she was gonna head back to the fair. she lives 15 miles from town she said whe would text me when she got there she also said how her mom was "upset" with me and this made my day worse cause i have been worrying about us maybe breaking up all week knowing her mom hated me didnt help cause that might push it to cause us to break up. so she came back to the fair. so we texted and i asked her what the plan was for the demolision derby that night cause her mom might not want me to sit with them but i wanted to go and i wanted to sit by my girlfreind. she said she didnt know what would happen then a bit later in our texting she said she was gonna sit with her family. and after that she kinda stoped texting me so by this time it was getting close to the time the derby started i went over there found her, i called her a few times but she didnt answer me. so i found her and she was packing up all the steer stuff and the steers and when she was done i asked her if we could talk and she ignored me i waiting for a bit and asked her again and she snaped at me. i asked her if we could just talk for a minute she snaped at me again but walked outside. we talked she said that she was about sick of me cause the whole thing and she was getting really close to breaking up with me so after talking about the whole thing a bit me crying for fear of losing her. she means alot to me we have been through alot and i trust her enough to tell her stuff i have not even told my parents about bad past issues and so i told her about how i am really scared to lose her and i am trying my hardest to keep us together and all that well we went to the derby watched it and after her family went to eat i wasnt hunrgy so she walked with me to my truck so say buy love you hug and kiss, she said she would text me and call me before she went to bed so w
