I broke up with my ex in December and we've recently tried to rebuild our relationship. We stay in different city's and haven't seen each other since the breakup. We've just been communicating via watsapp and phone calls. Recently he told me that a female friend of his asked him to donate sperm as she is ready for a kid and wants his good genes, and he is seriously considering it. I flipped. Do I give this guy a chance or do I let go for good?
