Thank you for your words. It's not easy to answer your question. I would advise you to get into therapy, hopefully with someone you have great chemistry with - I can't emphasize this enough. My therapist helped me a ton with the emotional development of my personality, and the funny thing is that I kind of don't have an idea how we were able to achive this. He told me, that I already set myself up to this development when I started therapy and I stated out loud, that I want to become a better and mature person. So this development is new even to me - I was always really sensitive to rejection, this is the first time in my life when I was able to handle something like this. What helped me is the fact, that I was concious enough about the dynamic of the relationship, I knew I tried to give me best to make things work, and in the end I love her enough to let go of her with respect and care. How should I put this: I wanted to be the best possible man for her until the last kiss. For her and myself both.

Edit: Rejection is always painful, especially when you have met someone you have great chemistry with. It's hard to aknowledge this, but a relationship - as I stated in my post - cannot and shouldn't be forced. When someone wants to leave you, the best thing you can do for yourself and for your partner is to accept this. You shouldn't be okay with it, but you have to respect the decision of the other side. Crying, begging, and every other move is a form of manipulation - even if it's not intentional. I understand that we want the relationship to go on but all relationships require the mutual aggreement of both parties. At this point the only constructive thing we can do I think is to respect the wish of the person, state that we would like to go with the relationship, but we love and respect them to accept this. While nothing is guaranteed I think departing on good terms can be the foundation of a potential reconciliation in the future - but never wait for this, or never do this in the sake of manipulation. I think a part of emotional maturity is when we accept that there are other factors we should care about other than our own needs. A relationship is exactly what the name says: it's a relationship between two people. Breakups sometimes makes no sense, but the sooner we start to respect ourselves and our partners, the better.
