My best friend died a month ago. It took their death to figure out the man who loved me for 12 years was someone I needed and loved and would get better for, but I know he doesn't love me ENOUGH to be in a relationship with me. His love is conditional, as it should be. If i don't get better, there is no chance. And who's to say someone new will come right in and sweep him off of my grasp? Then, what was the suffering worth for? I'll order a rope before the sun rises.
I think, if you're willing to give it a chance (I strongly recommend on seeing the right person), you could have someone who you'd end up with in a happy marriage.
Because, from what I can understand of my parents and many families, what really keeps the parents going is their children. Without them, the parents would be just like us; wanting to CTB since there'd be no meaning for their lives. Of course, I'm not saying only children make up their love..
Anyway, I insist on you checking the right person before actually setting up with them. Since there are just way too many instances of ending up with toxic people that make life a living hell instead. And, if you really would CTB over love, then just give it a final chance. If it works, then yeah that's a reason to live, if it doesn't, then u can always CTB
