>have exactly two people that I hang out with in this world: girl that I'm dating (T) and friend + his group (let's call him A)
>irrationally paranoid that if I don't hang out with A often enough we'll drift apart and the friendship is over
>have been hanging out with T a lot over past few weekends since we just started dating
>don't feel like hanging out with T this weekend, but feel like she'll be offended/hurt if I skip out
>feel like I need to catch up with A as it's been a while
>told A I'd let her know about this weekend, I hadn't gotten back to her, and now she's upset
>trying to control my annoyance so I just said good night, without actually giving an answer re: this weekend
Is it wrong to want to spend some time with my only friend in this world? I feel obligated to have to hang out with T when I just really don't feel like it this weekend.
If you don't feel like it, and you want to hang out with A to catch up, then man up and tell T exactly that, i don't see the problem, obviously don't tell it to her like you don't want to spend time with her, just make her understand what you want, communication is a core part of relationships.
