Okay...caution about dating someone...really unless you are done and over your marriage you might want to think twice...
Reasons:
What if you become so involved that you no longer want your marriage?
What if the person you date falls in love with you, are you prepared to hurt them if your W comes to her senses?
Two wrongs don't make a right...just because she has an OM doesn't make it right for you to date...unless you are DONE
Using jealousy is never a good idea...
I understand wanting that closeness and shared company with someone of the opposite sex...but really if you are still willing and wanting to work on your marriage you are playing with fire and someone will get hurt...
This is the time that YOU NEED TO FOCUS ON YOU...make changes that your friends will NOTICE...but don't feed them information to drag back to W....work on being the best man you can be...so that no matter what occurs in the future you will be better suited for a R that lasts...even if it is with your current W...
You are still very new at this...it hasn't been that long...but if you make the choice to start dating I can pretty much guarantee you that you won't get the results you want...especially if you do it with the intention of getting W back...I know she is seeing OM...but if you go tit for tat with her even if you get back together that will be a bone of contention on her part....(you gave up too quick...you dated too...how do I know what you did or didn't do....)
I would think long and hard on this one...
To take up the time so your not sitting around waiting for wife...take some nite classes....take up a hobby that gets you out...make friends and go out often...to the movies...for coffee...don't be so accessable...this will make you attractive...
Because honestly do you want someone back because they got jealous....or because they realized that they made a mistake and wanted to come back to you????
