I’m Ruining My Own Relationship

Hey guys so I (22F) have been dating my bf (23M) for 7 months now. Things are getting pretty serious and stable lately. I think that’s the reason why I started to look back into my dating life.

I’ve had my first relationship when I was 16, lasted a year. When he broke up with me I was devastated but also it was my college admissions year so I had that whole year the work for myself. So I did. I got into a college I wanted. Ever since I’ve never been single at all.

First year bf no.2, broke up with him when I was starting my second year (so we dated almost 10 months)
Second year bf no.3, same shit dated a year broke up with when I was starting my third year. I’ve managed to stay single for 7 months.
Third year bf no.4, started dating him in the middle of the year and surprisingly didn’t break it off the next year. However I did broke up with him while I was starting my fifth year.
Fifth year my current bf, I was single for 3 months before we started dating. It’s been now 7 months and I feel like I am always in a relationship. I adore him and in love with him so much, I think we might marry one day and he could be the one for me. I just wished I ended all of those relationships faster than what I did cause they all needed to end waaaay before they actually did. I’m so sad I’ve never even had a single summer in college and now I don’t think I’ll ever be single again.

At first I did all these because I didn’t want to be alone but this time I honestly fell for my bf. I just wish maybe I could’ve been single this whole time and we just started talking now. I would have so much time to grow up as a person it would help me so much and I wouldn’t have those regrets. Right now I feel like I’m always trapped in a relationship and I need to breath. I’m thinking of breaking up with him because being with him overwhelms me.

I don’t know if I should go talk to him about it and break it off or maybe try to work on those negative feelings and not ruin a perfectly fine relationship?
