I agree with those who have posted to say...time to take your life by the horns and leave him behind. Being a biological father doesn't mean that he can be what a true father is, or should be. Kelly's real father barely speaks to him, and yet he and his second wife have HER kids over all the time for meals, etc. It's like Kelly doesn't exist. For a long time, this bothered him, but now he doesn't give a darn, and he'd rather not be involved with that side of his "family" anyway because they are not family by the true sense of the word. Blood family isn't necessarily true family. There are plenty of adopted people in this world who can attest to that!
To me, you sound bright, motivated, and although you have had some trials, you seem to be well adjusted now. It is time to close that chapter of your life and move on to what you want the future to be. He's not going to come around anytime soon, and you don't want to waste time hoping or wishing he would. Follow your dreams and your passions and make your future what you want it to be. There are so many opportunities for the taking, and you will miss them if you focus on the past. If I were you, I'd delete his texts and change my number. He's being selfish and unkind to you just to make himself feel good. That is wrong, wrong, wrong. Time for you to deprive him of that opportunity. The most important love is the love you give yourself. Take care of you, be the best you can be, and appreciate yourself for who you are. You don't need his love or acceptance to do that. You be in control - don't let him be in control. He doesn't deserve any control.
Sending empowering thoughts!
