well. good luck man, but i think u messed it up from the beggining, u shuld have drawn the line from the sec. she started communicating with her ex. bt its H2O under the bridge now. so maybe wats left to do now is just try and patch thangs up. u culd start by ridding yo mind of guilt first, stop thinkin u r the loser here, u r not the only loser. she is also stands to lose. now u want things to go back to the way they was right. wat yu can do is just do wat u used to do when things was good btwn y'all. go out often. get goin with the ****y/funny stuff, be the great guy she fell in love with. that way her I.L will go back to 100, and the problems u havin will be overshadowed by the great time u be having. above all man, have a positive mindset while u are at it, cuz nothing messes up everything better than a negative mindset. have relaxed confidence too. (read some of the seduction science reports on relaxed confidence). that way, i think soon u be back on track
