Its not irresponsible if you really did love that man and was over your ex but then a few months after the propsal you fall out of love with him and fall back in love with your ex so thats irrisponsible? I DONT THINK SO! and i dont have to mention that i was on birth control for your peice of mind, hat shouldnt matter.
As a reminder. You have to respect that these are just comments and that they are originally out to help you with a complicated situation. Its good to know details (such as birthcontrol, how long you've been together, etc.) because it shows that you took care in the relationship. The details help us understand how to best give you advice.
Now, to the topic at hand.
Reminder that this is advice and of my own opinion so try not to take offence.
Birth control can have its faults. Most of the time someone will get pregnant on bc is not taking it everyday at the proper time. Though I have no idea how you used it. So its of no importance.
I believe your ex has finally found happiness and although he talks about getting back together in bad times, I really think you should leave him alone and let him live his life. Its odd that you feel out of love with your ex so easily and it seems it has happened again with your current fiance. Though I wouldn't be surprised that in a few months after you broke up with him again that you would fall back in love with him. realising what you are missing. I assume thats what happened with your ex to begin with (you realised what you were missing). I still believe that you should probably cut off contact with your ex. You may love him, but he loves someone else and shes having his kid. So, its probably best to move on take care of yourself, since you are pregnant. Thats what is truly important. The child that lives within you right now.
I feel very badly for your fiance. In his mind everything is perfect. This will tear him apart severly.
