Ive been seeing my boyfriend for a about 5 month now, the first few month all he could talk about was his ex. He told me he had dreamt about getting back with her, if he listened to a song he'd be like oh it reminds me of been on holiday, he'll bring her up in conversation if it's something related, for example I went to * university, oh my ex went there. My mum was talking about flowers n cost of them, he's like oh the most ive spent on flowers is 35 quid but those were sorry flowers I messed up etc. ive told him about this and he said its normal, ive asked him if he regrets breaking up with her and he said no it was amicable. I try to say to myself if They were together for 5 years in which he took on her child so I guess after that amount of time with a child involved coming to an agreement to split it must have been over for the both of them. Am I being too jealous and over thinking?
