Terribly Depressed after G/F broke up with me 6 months ago, feel lost, what now ?

I feel your pain. I am sorry to say this but if the colombian girl has lost interest in you there's no point in trying to keep that relationship going. You have a lot of problems on your hands but suicide is not the answer, its the cowards way out. You are not a coward are you? Take all your problems and tackle them one at a time. I cant begin to tell you how but I can make a couple of suggestions. I you don't want to get back with your wife, finalize your divorce as soon as possible. That's part of the reason why the colombian lost interest because you are still married after being in a relationship with her for 2.5 years. The girl is not going to make a commitment to you if you cant divorce you wife. Try starting fresh and taking it slow, on-line dating is not the only way to meet someone. Dont go into a new relationship until all your other problems have been sorted. Hang in there it can only get better.
