<human>: I've been friends with two Jess and Mitchell, people i met through work for about 4 years now. I met them as they decided to get married and they've been married for about 3 years now. Over time as I've gotten closer to Jess I've learned that her marriage is breaking down and she's been leaning on me for support. However over the past year its gone from support to us both doing some subtle flirting with each other. She has expressed several times that the only reason she hasn't left Mitchell is that she is scared and has mentioned off hand after drinking a few times that her and i are much more compatible and she wish she'd met me first. I feel the same way about her but I never wanted to admit that to her because she is already married.

Mitchell is a nice guy and a friend of mine as well, we play basketball and work on our dirtbikes together but the two of them just don't communicate at all and essentially its like two people just living as flatmates, not as husband and wife (she has admitted they don't even hug anymore, let alone anything physical). Jess wants kids and Mitchell doesn't which i know has been a major conflict point.

Jess isn't very happy at the moment and hasn't been for a long time, if she was just a friend then i would just outright suggest they break up but my problem is that i think both of us realise that we have a strong attraction to each other. We haven't done anything apart from some flirting but that is mainly because we both don't want to do anything while she is married as opposed to any lack of desire on both our ends. I don't want to suggest breaking up her marriage when i stand to possible 'gain' something from it as if it did happen I'm sure we would start seeing each other shortly afterwards. So, i guess my question is, should i tell Jess to break up with Mitchell? She would know why I'm suggesting it but i guess I'm just looking for some outside perspective.

Provide a brief overview of the text.
<bot>: Should i tell my friend, unhappy in her marriage, to breakup with her husband when I'm likely to start seeing her straight away?
