Have you had a long conversation with your boyfriend about any of this? From what you’ve said, it doesn’t necessarily seem like you two are a bad match for each other, but it does sound like there is a communication breakdown.

For example, that vacation you took with your brother… your boyfriend apparently expected you to contact him a certain amount and you contacted him a lesser amount but it was an amount that you felt was acceptable. I’m guessing you guys didn’t talk about your expectations for contact before you left, right? So you were both expecting different things. Neither of you were necessarily right or wrong there, it was just a communication breakdown.

The same goes for the time spent with other people. He may be expecting one thing from you while that isn’t working for you but have you talked to him honestly and directly about your feelings and what you need? If not, let him know that you do need to spend time with other people, too, and that it’s nothing against him, it’s just healthy for people to have friend relationships outside of a romantic relationship and that is a need for yourself that you need to meet. He may be receptive to that. If that doesn’t work for him or it’s not something he can give you, then that’s an incompatibility, but it may just be another communication breakdown and he may be fine with you hanging out with others once he understands more by talking about it.

So before you convince yourself one way or another, I’d talk to him about all of this. It’s definitely worth a shot if you really care about the relationship because that open and direct communication, laying out boundaries and spelling out each of your needs so that you clearly know what each person expects, might solve a lot of your issues with each other and get you back to really enjoying each other’s company more often. And if it doesn’t solve anything, then it’s more likely you’ll know you need to go your separate ways.
