Hi Worried, you raised a few points on the practical side:
- see if you can get the money before you leave, but chances are you won't see it again, so be ready for that.
- Have somewhere ready to spend the night when you break up with him. Ideally move your stuff while he's away. That's not so much sneaky as avoiding drama. I'm not sure how isolated you are where you live but keep your safety in mind, after all he's a drama queen.
- Go as soon as you practically can as he's sucking the life out of you.
- Go non contact with him as soon as practical, because he will turn on the charm to keep his control of you. If you don't give in he may get nasty.
- How he copes is not your problem. Really. He'll find some other person to suck dry and manipulate before you know it.
- How to tell him? Well you could email him while he's away, or tell him in person. Just keep your own security in mind. Maybe this is something you could discuss with your Dad, or friends who've been through breakups.
