Should I go ahead and text him/call him and tell him that right away? Before any of this happened I invited him out to a show, then found out my ex might be there so I decided not to go but he had already bought tickets so I felt bad and then last night I told him I'd go because I felt a bit pressured and this morning now I know I can't go. I was just going to lie and say I was sick or something but should I go ahead and tell him I realized I got involved with him too early and I'm not in a place where I can be intimate with anyone right now and that I don't want to go to the show or hang out tonight?
We're going on a roadtrip with a few mutual friends this week too so we can all see my friend who lives in another state. None of us have seen her in a few years so I'm most definitely going. I'm going to tell her the situation (not any details because I don't want to betray my other friends confidence but just that I'm uncomfortable with him) so that we can figure out sleeping arrangements (we're all spending the night at her house) and I'll be able to sleep in another room with one of my girlfriends instead.
I've been in situations like this before with guys but it wasn't an issue because we didn't have mutual friends and we didn't run into each other at school or whatever on a regular basis so this is a bit harder for me.
