Every night both me and my girlfriend have spent the night together by ourselves, we've had sex. I spent the past weekend with my girlfriend camping at a beach. The first night we were kissing a lot and i started making more moves on to her. she then told me to stop and that she doesn't want to have sex, because I was "forcing her". Previously this week she didn't want to because it hurt her vagina because we had just had sex a lot for two days. We did anyways, and she cried while we had sex. I didn't know this at the time, since she was covering her face which confused me. she told me afterward that she was crying and that she didn't really want to have sex. She only did it for me. I told her i was sorry and would have stopped if i knew. We ended up having sex again but she threw me off because it hurt her so bad. So...I think she was mad at me the first night we were camping because of this, which is why she said i was forcing her. In reality i wasn't though because she wanted to but dealt with the pain. So the second day we end up going to the beach and i drove so she could drink. I end up drinking too much, so she had to get sober and drive. She was really pissed about it. The second day we end up getting drunk at the campsite and shes being nice to me and pretty much shows affection to me with kisses and holding my hand and stuff. So we end up going to bed and i try kissing her but she doesn't want to. I ask her why and she tells me that she's mad at me about getting drunk when i was going to drive and that she had to stop drinking. I'm wondering, is our relationship falling apart? If so, what should I do? I know i was an asshole and apologized to her. I tried making it up to her by driving her home which is a 4 hour drive.
