I really have nothing to add either, because everyone has given you good advice and I can't possibly know what you're going through. I just know that I'm sorry you have to go through it! I'd definitely take the advice about meeting him at a neutral location for him to see your daughter, and he should never EVER be on your computer or anything else of yours again!
I'm really proud of you for coming here to get support for this instead of looking for comfort in food. I think that's a HUGE step, and one that's really difficult to make, especially in as stressful a situation as you have going on. I don't know if I could be that strong -- I think you're amazing!
