Here is the thing,

I have (had) a 13 year marriage with my ex wife (we are married but separated).

Most of the separation guilt is mine, i had an addiction to online gaming (i "woke up from it" about 1 year ago).

From last August to December my ex wife told me that she wanted to leave the place (we have 2 kids, both around 32/33 years old) and since i love her (yes i know that and maybe i also know that is not good for me at this point).

She left the house (near me) in last December, and we hang out in our different houses (with some kind romance/sexual relationship until 2 months ago).

One and a half month ago she told me she knew a man in her work (its more educated than me, more successful in his profession than me, and has about 39 years old). She says that she likes/love both of us but doesn't feel the "stomach butterfly" effect with me.

I tried to stay away for my own "health" and for my kids. but she keeps trying to ask me to hang out, watch movies at her place, and things like that, she also asks for help with things that she doesn't know how to handle (things that i used to take care when we were together, like most men do, she even asks me advice about her clothing (patterns, colors, shoes, bags, etc)

I usually can "read" women quite well (and respect them, but we are all "animals") , but since i am clouded with my feelings i have no idea what is all this about, she knows i love her, that i want to get our relation back and that i would do anything to achieve that (lets be honest, i love her and i am an idiot because of that).

I would like an approach from someone that could give an honest advice regarding this issue, and i will reply back so i can make a real point of view regarding this things.

Thanks in advance
