PLEASE READ‼️i need advice bad.

so me and my boyfriend have been together since i was 15, i’m 19 now, he has recently told me he wasn’t as in love with me as he was 4 years ago, and it hurts bad, i feel like IM not good enough for him or that i changed too much (we was also saying that we’ve both changed, but everyone does over time right?) and what is really confusing is that he wants to “go party because why the f**k not?” and he wants to “meet new friends, and some will be girls”. he also talked about how he wanted to focus on his life and not a relationship too but that he loves me.

i’m not controlling, i’ve never told him to block anyone, including girls, except one of our old mutual friend who started a lot of drama and rumors and i told him i wasn’t comfortable with him talking to her so he blocked her, now she’s recently unblocked for some reason and when i ask he just says he doesn’t remember blocking her or that he needed to ask where her husband is, she made accusations that he’s tried to get her to have sex with him, that was like 1 1/2 years ago. (she’s known as a liar and when i asked for proof she couldn’t give ANY, and she said he’d call and text her all the time, yet there wasn’t any recent phone calls or texts)

he told me about this last night, and he said he didn’t want to give us up but he doesn’t know what to do.

anyways, i want for him to fall back in love with me, how do i do that? or should i prepare for us to break up? please give me some encouraging advice, thank you in advance ❤️

EDIT: we broke up, i’m doing okay, thank you for all the kind words:)❤️
