I'm 31 just like you. I share your pain and I feel so sorry for you that you have met with this type of person --- such a jerk. But what made me wordless is your obsession over him. You let this guy continue to have influence on you, still open almost every channel of contacts and connections with him, and also your non-stop same type of questions "Why he do that?, why he do this?"
May I ask you why? Why doing this to yourself? Even I don't know you before, I feel that this is absolutely unhealthy and come on... we are 31 now!
When my ex dumped me 2 months ago saying that he never loved me and he just can't pretend any longer. I was in deep shock, after all the nice things I have done for him for years. I feel being used, being lied to, and feel so worthless. I spent time figure out what's going on and there are thousands of stuffs going in my head for weeks. Then I just come to a conclusion that "I deserve a lot better --- than this jerk who always suffer me, the one I deserve will be the one who is a good kind person in his character, who won't leave me for other girl, who won't lie to me, who won't cheat on me, who will always stand by me, and who truly care for me." And the belief that I deserve better give me strength to get over him and I know that one day I will totally get over him. I still feel so hurt sometimes and think about it a lot but my strong will to keep moving forward not backward make me get through it day by day.
And you know what I have done since the day he dumped me? SINCE THE FIRST DAY HE DUMPED ME, I changed all my numbers he knows, I blocked him from all possible connections he had with me, I even blocked all mutual friends, and blocked all the emails, and tell mutual friends to totally shut up about him, so he has no single way to reach me at all nor do I care if he tried to do it. And for me, do I want to contact him or visit his Facebook or ask some friends about him? Yes! I really want to do it a lot. But again it’s my strong will to move forward and I realize that doing all those things are useless and will only cause me pain, so I never do it. I never contact him in any way at all and I know that this is the right way to go. Dignity and pride make me feel good about myself.
You should stop figuring out someone as it consumes so much energy! And all your “why” questions come up with only one answer that “It’s so clear that he is not a good person and even clearer that this guy doesn’t love you at all!”
I think your problem is that you never really want to give up with this guy, to be honest. You stuck and you obsess and you just can’t quit this cycle because deep inside you don’t really want to do it yet. You still seem to enjoy suffering yourself and enjoy texting and knowing about him and then come here and ask “why” and “why”. I think you should ask yourself “Why I still holding on to this?”
This has to begin with the strong will inside your heart and your mind that you want to end it and really feel enough with it. You have to see by yourself what’s good and what’s bad for you. It’s so clear for us but maybe it takes more time for you.
You have to love yourself. I don’t think you do. Sorry to be so straightforward but people who love themselves will not do what you do to yourself right now. As for me, even if I cry for 24 hours everyday for months (which I’m not!), I will never ever contact or want to keep in touch or want to know anything about anyone who dumped me, or used me, or lied to me, or suffer me. I don't want my dream guy waiting for me out there for too long by stucking on this past nightmare. Case closed.
