Feeling like I'm not wanted

Never done an on-line support group before, but here I am really feeling bad. I've been divorced for about 10 years and have been dating and living life in a fast and sometimes dangerous way.
I've been in and out of relationships but the most recent breakup tore me apart inside. It hurts like when I went through my divorce. I've lost sight of who I am, why I'm here, what to do next, not wanting to be in relationship again. The thoughts go on and on. I've lost alot of sleep and am just trying to maintain.
I know people come into our lives and go out of our lives for a reason. But after taking a hard look at the dating scene it really is tough at my age to play around with my emotions and feelings. Too bad for me cause the last relationship had no feelings and that is what bothers me. Got dumped hard and stomped on my heart while I was vulnerable. She wants forgiveness from me but I can't right now - I will forgive her when the time is right.
I've been looking at my past patterns and it's not a pretty sight. I think I've dipped into relationship codependancy and didn't reaslize it until now! Dating just to have fun and be with someone is OK for awhile but then the emotional price can be expensive.
I think what I am experiencing now is the result of a cumulative effect of going in and out of relationships over the years without looking after my best interests.
I'm been pursuing various areas of healing and do I need it.
Your thoughts and comments are welcome.

Not unusual what you are feeling, you are looking to have your life fulfilled with someone that you can wake up to in the morning and have a meaningful relationship with, I would just suggest that you take time for yourself and heal... Learn to find joy in who you are, and realise that you will be OK! Once you feel you have healed, take a lot at yourself and see what maybe you can bo to be a better partner to someone... But realise, that There is not much you can do if someone doesn't want to be in a relationship with you....Honestly, most people go thru this in one form or another....

it's ok that you don't feel like forgiving right now, but at some point for your own sake you forgive and forget...
