Oh hun, welcome to the forums and big

! Your ex is just lashing out because he is mad that you haven't fallen down and collapsed unable to cope without him! He's a childish, jellous arse of a guy and you are so much better off without him (no matter how painful the prospect of being on your own might seem...). I know how painful infidelity is, and just how much your heart is breaking with the realisation that the man you were prepared to marry is not who you thought he was at all... All I can say with regards to that, is it WILL get better in time (I promise

) I know that facing single parenthood is very scary, and nothing I can say will make it less so... but keep it in your mind that many women do a better job on their own than some couples do - I'm sure you'll be one of them, sweetheart

Everything happens for a reason, and it's better that you've found out now so you can focus on your own little family of just the two of you, than to bring the baby into a family including that selfish man, only to discover what he was up to later on in the relationship and have your darling baby go through a break-up...
I'm so sorry for everything that you're going through. If you ever want to talk feel free to pm me or add me to msn... x
