Search Results: building trust after cheating

There’s this guy who has some trust issues. When I met him, he said he doesn’t want to get into a relationship because of that, but we were both interested in each other and it was visible. After some time, I got tired of him behaving hot and cold and asked him to be just friends. 2 months later he started dating another girl (who he said is the best girl he’s ever met) who cheated on him. After about 3 weeks after they broke up, he started talking to me again and we’re doing really great, but he’s also talking and, as our mutual colleagues say, flirting with other girls.

What should I do about it? Is there some way to show him that we could be great together? We used to have a really good connection and we’re slowly building it again, but I feel like he doesn’t take relationship with any girl seriously.

So after having been played in my previous relationships, lied to and cheated on, I feel like I have developed some trust issues. It’s been building up for some time, but the final relationship where I found out he was cheating changed something inside me completely.
I’ve started having these random thoughts pop up in my head like ‘oh that’s a nice shirt my brother is wearing... wonder if he’s about to see a side chic’ or ‘This dude looks hot and seems smart - he must be a good player’. And this happens all the time, whether it’s a stranger or someone I know, (and know they wouldn’t be a cheater, but can’t help but feel like that). In the back of my head I started subconsciously seeing a liar in every guy, thinking that some are just better than others. I even stopped wanting a relationship at all, as I feel that at the end of the day they will just play me and hurt me all over again.
Is this what you call trust issues? And how do I deal with this? People say that I’m still hurting and just need to heal, but I’m not sure, - I’ve been hurt before but I’ve never felt this way before... it’s something completely different. I’m well off so I could afford seeing a psychologist to talk about this - do you think I should? Or would it be unhelpful and do I really just need to wait?
