REALLY? “My bf keeps lying about his Ex and other things. Should I trust him?” You really need some direction on this? Okay, here it comes…stop being an idiot. Went on holiday with ex, found out from his housemates; you gave him the benefit of the doubt?? on what? That while they were out of town together they slept in different beds? Let me tell you, if I go out of town with my ex…sex is going to be involved. Kissed another girl after your 2nd date a year ago. Sounds like you should have gotten a clue a year ago. these two incidents are not the only ones I hope you know. People, women, love to live in denial because there is NO WAY our boyfriends, husbands, etc. would ever want anyone but us. Well, yours so far has wanted two and all the others in between. Dump him, you look like a fool, especially to his housemates and all their friends, and so on and so on. Take the door mat off your back and stop embarrasing yourelf by being ok with being second best, second fiddle, second everything. No man is going to respect you “when you give him the benefit of the doubt”. To him…“I got away with it WOOHOO”
