I completely agree with lucky Jim. If you're up front and honest about your situation and she respects you and waits for things to be resolved, without stress or hassle, then that's a good woman.
I would however suggest not to rely on dating sites. Do different things. Dont think about trying to replace... .it don't work. I would say tho flirt with women... .be happy and smily and kind and before you know it, you have a different circle of friends who care about you... .believe me... .i know, with what ive been through... .get out of your comfort zone and try something you would only dream of. It's not as hard as you think
