What I want to do is hug you and make it better I want to tell you what you want to hear, but I wont - I will tell you how it is, because that's what you need to deal with right now :(
Great, that's all I need
We have a 14month old DS - He hasn't been in touch since he left
He's fallen out of love with me
He's probably seeing someone else :( But whether he is or not you have to accept that right now he doesn't want to be with you, he doesn't want to be a family. IF you cry, beg, etc to make him come back (out of guilt) it will be shit.
You will throw it in each others faces when you argue (which you will).
If you make him come back when he doesn't want to, the chances of him walking out again when you have a newborn baby is HUGE and you would be in a more vulnerable state than you are now to deal with it.
Stay calm. Keep your dignity - it will come in handy later!
Tell him if that's what he wants then that's what he should do.
No matter how hard this is (and it is!!) tell him that you will, of course, expect him to have DS 50% of the time (do not back down on this). He must not be allowed to just be a Disney Dad. DS is his responsibility too.
YOU decide what you are going to do about this baby, on the basis that you will be a lone parent, then TELL him how it will be. He is not the one who would have to carry it and care for it while it is a newborn and he is not the one who would have to have the termination - this is your choice and yours alone.
I know it's not what you want, I know you want to beg him to stay and you want him to be the man you fell in love with, but right now he's acting like an enormous wanker and that is how you should view him.
You will either get what you want when he realises what a complete shithead he has been (at which point YOU can decide if you want him back or not) or you wont but you will have your dignity.
Stay strong - it is fucking hard :(
