I honestly know how you feel & this is not a pregnancy thing! My ex boyfriend and i were doing just great until his ex come back in the picture.. I had a miscarrige and found out in that week i had it he had dated her again and was still sleeping with me! I absolutely hate her guts & every time i hear her name i cringe.. He used to always answer her calls/texts infront of me and when i text him it would take him 5 hours to reply.
I'm now pregnant with his child & he doesnt even want to know me until he wants some pleasure! I stay at his and he sometimes stays at mine.. but if i ever found out he was talking to her, and if we were ever in the same house and he told me to leave i think i would blow my head off! Sometimes i wish i do, but im too nice /:
