Is it normal to not trust my girlfriend?
Ok so i dont trust my girlfriend. The reasons for this is other lads are always hitting on her, for example slapping her as and stuff like that and she wont tell them to stop, this gives me the impression she likes other guys touching her. Secondly she is always around this lad she went with once after a night out and she laughs at everything he says which is always about sex, which pisses me off because its basically flirting. She shares a taxi home with him every night, she says its cos they live close which is understandable i guess but i still dont like i, should i say im not happy with this or will it make me sound like a dick? And thirdly, probably the worst thing ever. She got a txt from her friend and i looked through her phone briefly and seen her ex boyfriend was texting her, this hurt me big time. She took the phone off me quickly and i think she deleted her sent messages and showed what he wrote. It was nothing bad, he asked her a question which was ridiculously long, quite like this. For some reason i dont talk to her about all of these seriously i always joke around about these reasons and never tell her how i feel about her getting a taxi with him, for example, when she gets in the taxi i say to her jokingly 'have fun you two' or 'not too much kissing now' something along those lines. I think about her and him together and i feel like killing something, oh and btw this guy is like one of my best m8s so it makes it worse. She says she would never cheat and hates liars which i dont believe to be honest. Sooo wtf should i do with this situation, say to her that i dont like her being with him alot or keep it to myself?
