I think you’ll cope far better than you think on your own, once you’re off the emotional merry go round he’s creating, I imagine it will be easier still. I’m sorry to say it, but it does sound like he’ll tell you what you want to hear when it suits him, and thats really not fair on you, given you’re 14 weeks gone, the stress on you and the the baby isn’t good. Perhaps you need to concentrate on yourself and your toddler for now. You need some peace, and it doesn’t seem the current situation is providing that for you.
Is there no way you could get back to somewhere closer to friends and family maybe?
