Things aren't looking good here guy.

Go purchase a handgun, question her about the texts while flashing the piece.

If that's to Hollywood then maybe just play it cool and try to catch her in the act, pretend the texts don't bother you.

Buy some cheap surveillance equipment from radio shack and waste all your time eating sbr pizza and drinking coffee during the stakeouts.

Or finally you can get on your knees and thank god that this happened before having a baby and being stuck with child support for the rest of your life. I don't think you want to log in everyday and have to ship your 12 points to this gal forever now do ya?
