I (18m) feel trapped with my (18f) gf

I know I might be overthinking this too much but I just wanted an outside view. Me and my girlfriend have been dating since we were 15, we’ve had our ups and downs in our relationship. But in recent times I’ve just felt so trapped.

A few months ago she would always ask me to make time for her when I had football practice every day until 6pm and games on Friday. On top of college level courses. I never shut her out, but I just couldn’t really hang out during the week due to my busy schedule. She would complain about it to me all the time, and I’d constantly feel like shit for not being enough for her.

As soon as football season ended I made considerably more time for her. But as soon as I did it was like she switched off. All of a sudden she’s hanging out with her friends way more than me, which is completely fine with me. But it gets to a point where I ask if she can spend a little more time with me, or if we could all hang out together, and she complains about it.

On top of that, there’s a good chance I’m going to be moving back to my home country next year. So I’ve voiced my feelings that I feel like we’re on borrowed time and I’d like to spend as much time together as we can. The only reason I’d stay here is for her, the weight of my family’s future, my future. I told her that I’d only stay because of her and she just stormed off and said “do you really think I’d be happy after hearing you might be leaving”

When I tell her my issues she gets upset at me, and if I don’t apologize or try to fix the situation we just stay in the pissy mood we’re in. This isn’t the first time things like this have happened. It’s the same shit different story. She begs for forgiveness and promises change, then a week later she’s back to how she always is. I put on a smile but then as soon as she walks away I feel like ripping out my hair. After one argument I kept kicked my car out of rage and ended up fucking up my toe pretty badly, and when she asked what happened I just said I was pretty upset and was kicking shit.

For some reason that interaction made me realize that for some reason I am incapable of blaming her for anything. But then I started to think about how she treats me in that regard. She blames me for everything, like one time she was doing something to her hair and asked if I could be there so I could see the process, I asked her for days and days to make sure I was there when she did it. And one day I took a nap for an hour and a half, and she told me she was doing her hair, and that I wasn’t responding so that’s why she didn’t ask me to come. She didn’t text me at all that she was doing it.

In the end I just feel like I can’t get through to this woman, it makes me want to cry. It’s so hard for me to try and leave because of all the time and effort I’ve put into this relationship, I really want it to work, but I feel so trapped. Like suffocated to the extent where it manifest into reality I sometimes just don’t breathe when I’m around to her. I’ve told her that I can’t keep doing this song and dance with her. It’s really killing me inside. Im not saying I’m a saint, but I keep my head down and just try and please her most of the time, but I can’t keep doing this. So my question is, is it time to end this?
