Job and Gordie already posted wise advice to you. I'd also like to say that MLCers tend to 'affair down' - partly I think it is a practical thing - 'affair up' women probably run a mile and don't give them the time of day. But also I think there is something about needing to find your own level in someone else - find someone also in crisis or with issues...I think that is what happens.
In my case, OW is intelligent and attractive and much younger. But also her last R was an affair that led to a marital breakdown and she cheated on that guy with XH - ie: she is an emotional mess and the fallout around that is pretty immense...
So, please don't for a moment think that OW must have something 'better' than you - I have never once seen that be the case...
