Please...I need advice on this, relationship problem?

Sounds to me like U need to cut the tie that binds! She will not change! She likes the idea of leaving and knowing you will be sitting there...waiting patiently for her whenever she wants to return! And that is BS! And besides that you met someone that you really like and want to spend time w/! Whether it causes her to need psychiatric help is really not your problem! U stay w/your wife and U are going to need psychiatric help!! Basically it comes down to either her or you! I say divorce her and get back w/the woman you met while you were separated! Make yourself happy!
