Well me and this guy went out like 9 years ago and it didnt work out..so we still continued to mess around since we really loved each other..so I found out one of the girls that he was talking to gets pregnant.so I end up with a dam rebound guy who I end up getting pregnant by since I heard about my ex. So years passed and me and the ex still kept in contactand messed around on the side..he had problems with his wife and I had problems with my hubby…so we would see each other on the side..my hubby is in and out of prison and I really dont love him I now have 2 kids and still with him. My ex got divorsed but recently on his bday he got with the ex wife and now she is pregnant..my hubby is still in prison, wich I think I’m gonna file for divorse now..but noe my ex is living with his ex wife again.. Because she is having another son..now I see my ex atleast 3 times a week..he isnt in love with her..he tells me im the one he loves..smetimes we talk all night cause he sleeps in the living room..I’m confused..he told me that he was gonna move out and he was just gonna leave her the house..cause of the kids..I love him allot and wanna be with him but I just dont know what to think!!!
