You have to realize that these girls weren't in any kind of state to have a normal, loving relationship.
A good majority of them kill themselves over self-esteem issues that typically arise from being a whore. It's unfortunate but it's the truth. Keep in mind those are the normal girls. The girls who are capable of normal lives, capable of being a loving mate, etc. You know, the girls that don't want you. The rest of them are going to be mentally ill messes; devoid of empathy, incapable of love. Women who are borderline, histrionic, bipolar, etc. often go to the extreme of attempting suicide (which they often fail). And when they don't succeed at that, they're going to be doing even more extreme shit. Shit like randomly stealing your car and going to a different country, or slicing open their calves so they can tell the police you tried to murder them.
Please don't try to convince yourself that any of these women are "waifu material".
