Sweetheart, he's messing with your head. He has had a little woman for 9 years. He hasn't encouraged you to develop new friendships, or interests or a career. He hasn't built you up.
Last week he panicked. He had agreed to buy a home with you, which meant that if your relationship broke down, you would be entitled to half of it. You have been married for a while. You will be entitled to a decent settlement, if you decide to return to the UK.
Once there, you may need to rent a room in a shared house, but that is a chance to make new friends. You can also look at your job and whether you can move to somewhere better paid. It is hard, but I have been there and so have others. I started again at 34, feeling a total wreck, only wanting the man I knew I couldn't have, with no confidence in myself at all. The first 3 months were horrendous. The next year was hard. The following year I was in a new job, with a new man and now have a lovely home and 2 children with someone who has my interests at heart. A friend of the same age went through problems in her relationship but battled on. Ten years later he left her, when she was 42, and although she has started again and met someone new, she lost the chance to start a family of her own. He, on the other hand, moved straight on, married and had children of his own.
There are lots of possibilities out there for you, if you can get through the next few weeks. It is horrible having your heart ripped out. Nothing will hurt as much as what he has done to you this week. But you can get though it. You can move forward and support yourself and find a future with people who love and respect you, and want the very best for you.
Thinking of you.
