How to know when to end it

Hello, so I’m considering breaking up with my boyfriend. But I’m not sure if I’m just highly sensitive or if I breaking up with him would be the reasonable choice. He(M20) and I(F20) have been together for 4 months and it has been a wonderful time, or more so it was the first two months or so. The honeymoon phase is over for me now, and I’ve just realized I’m more so annoyed by him than happy because of him as of late.

He makes inappropriate jokes, about pdophilia and other disgusting things, things that should not be joked about. He has repeatedly said his friend tried to “rpe him” because he hugged him from behind. I’ve also very clearly expressed my displeasure at such “jokes” but he isn’t stopping as far as I can see.

Also every time I’m so much as angry or emotional he says “I must be on my period” which pisses me off so much, since it feels like he’s indirectly calling me hysterical. That just may be because I am sensitive about such matters, so I’m not sure if I’m justified in feeling that way.

And today, after him not contacting me at all yesterday, I sent him a message saying I was late(which I never am for work) and he just straight up said “Well you could just have woken up earlier.” I must admit that that pissed me off too, especially with not having any contact with him for a day and then him being all passive aggressive like this. I wish he could just communicate if there’s anything that he’s not satisfied with.

Now it of course it isn’t all bad. We know each other well, he’s met my family and they’ve welcomed him with open arms. He’s my first really serious boyfriend and thus I feel like I’ve put in a lot of effort to make sure we could be mature and talk about things if they bothered us. He also picks me up whenever I’m out late so I don’t go home by myself. He gives me really considerate gifts so I know he listens to me when I talk about my interests. He gives me chocolate every time he comes over just because he knows I love it so much. But this are all things he does for me, so I’m not sure if our relationship is superficial or not.

We celebrate anniversaries, valentine’s day and we even gave each other a christmas gift even though we hadn’t been together for such a long time by then. And we’ve had such fun dates together. Just two weeks ago he picked me up spontaneously and we ate takeout and took a walk, just holding hands and talking - that was really nice.

But when the good times become fewer and fewer, is it worth it?

I really do love him, but I don’t want our relationship to become one filled with resentment. And we’ve already made so many plans for the future. He was going to be my plus one for a friend’s wedding, I was going to be his plus one for his friend’s wedding too.

And I just... I haven’t had sex yet, and he hasn’t yet either and we’ve been having healthy conversations about things like that, and we just both came to the conclusion that we would be each other’s first. But I think he may just be a bit too immature still to have a relationship like this, and if this doesn’t work out I still want to be his friend. But I don’t know if me having second thoughts about him may be a sign that we should take a break or some time away from each other.... I do not know and I would really appreciate some opinions here!
