I have been feeling awfully guilty for the last week Emma, he is a good person who loves me so much, but these days that just isn't enough. Today has proved just how unhappy iam in this relaionship, it was the first time we ever yelled at each other (or rather the first time I have ever stuck up for myself and said what I really feel!), So now that I sit here I am on the verge of tears, but it is blindingly obvious that I am doing the right thing.

I think you should discuss a plan with him. Like you say a trial seperation wont be a true indication of seperation cause you wouldn't really be out on your own. Maybe live apart for 6 months, once that 6 months is up reassess both your feelings.

Please try to stop beating yourself up about breaking up your family, even if you feel the reason for splitting is so small, there is still a reason that is big enough for you to consider splitting. Give yourself a break and so whats right for you. I know how extremely scarey the prospect of going out on your own is, but sometimes we need to do it for ourselves.

In answer to your OP, I am 100% sure I will be much happier when I finally move out with DS.
