How the heck does a 35 year old male meet women?

i was with a girl since i was about 24 and she was 21. we have a beautiful 5 year old girl together . we split up last april and tried to work it out because of our daughter and just this jan we realized that it was worse to stay together because fighting in front of her wasn't good (although we never did very much)..so anyway she has been out with other guys and don't seam to even care..AT ALL.. so i have been trying to meet people and just cant seem to do very good at it. i think if i met someone it would be easy to move on and not care either . so now i am 35 and not bad looking but i tried stuff like myspace,face book (witch i feel i'm too old for) i joined a gym, i shop in the frozen food section instead of the cake isle...lol just kiddin and nothing works...am i to frickin old or what? i don't feel old and people always say i don't look 35
