<human>: So I feel like this whole thing is a little bit complicated. Or maybe it's not, hell if I know, that's why I'm here. but anyways, here's the situation: My boyfriend and I have been dating for 6 months as of yesterday (3/17) and relationship has been a little bumpy. Or maybe very bumpy. So I'm still very good friends with my ex. He and I parted on really good terms, his family loved me, we saw no reason we couldn't be friends, even though our relationship didn't work out. Well my current bf never really understood my friendship with my ex as he has never maintained any sort of contact with his previous relationships.

But anyways, the part where things get complicated is that we have a lot of trust issues (he with me, I trust him 110%) but those are all my fault. I've lied to him several times (each time pertaining to situations with my ex i.e. I told him I'd say one thing but said another) because I didn't want him to get angry with me for talking with my ex. But the point I'm trying to make is that there isn't a whole lot of trust right now and that's a big problem that I am working towards fixing. Now comes the next problem, his parents have invited me along on a very nice and rather pricey vacation right after the school year ends and after that, he begins clinical rotations for the next year (pharmacy school) while I will most likely be abroad for an internship. 

So the part that's making me feel trapped is that, I'm not sure that we are even going to last the summer because I don't know if he and I will be able to handle the distance + the trust issues but it would just look like I used him for the vacation if I broke up with him (by the way, the vacation has already been booked and everything and there's no way to do anything about that)
Any advice??

Provide a brief overview of the text.
<bot>: bf doesn't trust me, kinda think we should break up, being taken on vacation, don't wanna use him.
