Fair enough. Real life issues does not internet fun make.
No man, that's not what I mean and neither is disrespect. I mean that people I respect (including myself) have gone through being unloved and I feel I get what you are saying. Love is tricky and different for everyone. Do not validate or invalidate your concept of love via the experience of others. For example, no one in this thread has talked about being in love with someone while not being in love with one's self. Been there, done that and personally, I know that love isn't enough. Sometimes to do the right thing one has to say, "I love you, but I'm leaving and I'm never coming back." I feel like this question could be better phrased. "When are you in love enough to make it last" and to that question, I am still finding out that answer. Chin up, in any case.
Title question was asked to me by a young man who thought that because I was with someone that I would know the answer. Ha ha ha. Ha ha ha. When are you in love enough to make it last? Answer: you don't know this until it lasts. At some point, you might say "I'm not leaving this person. I'm staying with this person as long as possible." it might not be the being "in love" that makes it last -- it might be all kinds of other things too. Good and worthy things. And just enough of that sticky love stuff maybe to hold it all together.
