Still haven't made a decision yet. Should I stay and keep giving him chances to do his part in this relationship ? Or do I go and just be single and just cut all ties ? I really cannot sit here and waste another year or so waiting for him to mature and be the type of man I need in a relationship, it's been three years so far and I'm starting to believe he just don't want to be affectionate with me at all and I know I'm in denial because I know those feelings I once had for him , the excitement in going to see him , the love , the passion, it's all gone , I don't feel anything towards him and I feel like I'm just saying I love you so he can hear it but I'm not sure I really feel it. Everytime I give him chances it's back to the same shit just a different day. I don't want Kai in a broken home but I feel like I'll just be cheating myself out of true happiness in my life .Am I being selfish ?
