Hi uhusti

Welcome to PC......

I read your post and will try and put my female persepective on this.....remember it is just an opinion.

First were you and your wife married young..? ie had your ex wife had other significant relationship before your were married.....?

I'm not say this is mandatory...I just asking because of her behaviour during your marriage (and by no means making excuses).

It seems that she is searching for something or someone to make her life feel fullfilled......? In more ones than on....or she may like the attention of others...I don't know.

Her reaction to you now you have a new friend is one of ownership and maybe she see you as the back up plan if nothing else come along.......I'm just grabing at straws here.

But I think your ex is searching for something and hasn't find it yet but doesn't what to let go off what she had/has with you.

A bit of having your cake and eating it as well......

I know this is a tough call but if you feel that you have done everything to make your marriage work. Then there is no reason for you to feel guilty.

You deserve to have a loving and happy relationship with who you choose.

Hope this helps a little.
