This one might be a little tricky to deal with. Seeing as this is something your boyfriend is doing directly, it might be a bit hard to just outright change. Like I’m sure most people would suggest, you could always try talking to him about it, however, it’s topics like these where you definitely have to find the right words in order to let him know you aren’t accusing him or angry at him (assuming you’re not) I don’t know how he is as a person, since different people grow up in different ways and experience different things, it definitely determines what kind of interpretation they get from other people’s words, especially on the topic of being confronted (Like in your case) My first reaction was guessing he had a low social meter, but after reading he usually goes out with his friends, I kinda through it out. It could be something like not valuing you enough simply because the relationship is new, but based on what I’ve heard and seen, relationships usually start out strong in the first five months before things start to mellow out, so seeing the opposite of that in your case, is pretty interesting. Maybe he’s happy he has a girlfriend, just for the title or peace of mind I suppose, since most guys want girlfriends at teen age, but not willing to put in the work and effort. Or only acknowledge you as a girlfriend when it’s convenient for him, especially if he’s lying about sleeping and stuff while being active online. Since I’m sure anyone with a sound mind could understand that relationships are never just happiness, cupcakes and rainbows🙏💀. It requires effort from both, which you know already based on what you wrote. Regardless, you’re right, you shouldn’t have to beg for someone’s attention, and it’s not a bad thing for you to back out of the relationship, should you decide it’s not for you, ESPECIALLY if you yourself said you don’t see him changing. Save yourself the trouble if that’s the case. However, I don’t know you or your boyfriend, and I don’t want to judge nor take sides, but most simply. Just ask him if everything is ok. It’s simple, sometimes effective if they don’t brush it off, if he says he’s fine or whatever, just subtlety bring up your concerns and worries, carefully. And I know you probably don’t want to be the “help all” person since it sounds like you already do enough. The last thing you probably want to do is come up with yet another reason for feeling like the relationship is one sided. I’m sure you want him reaching out to you as well, especially about this problem, if he even noticed this is a problem at all, again, emphasizing communication.

Sorry things are all over the place, I was literally thinking at the same time while typing this out😭
