<human>: Condense the text into a few key points

It's been 4 months since my ex and I broke up.
The reason behind the breakup was because she grew tired of me and wanted to do more with her life.
I really loved my ex till the day she told me she wanted to end. I blocked her off Facebook and any other social media websites to help myself get my mind of her.
But yet till this day I still stalk her on social media websites to see how shes doing. 
I dream & think about her almost everyday. I tried hanging out more with friends and doing other things to keep my mind away from her but it's not helping at all. I miss her so much I wish I could go back in time to experience these 2 best years of my life again. I've never talked to her since the breakup because I want her to forget me aswell. 

How things are going now:

I've known a girl for 5 years now and we started hooking up (having sex, kissing & holding hands) Just like a regular couple. But im not feeling the same feeling I had with my ex. She told me she loved me and I told her I loved her back but in reality I really don't feel the love feeling I once had with my ex. I don't know how I should tell her. She will probably get pissed but it can't go on like this.  My question is how I should move on without my ex and how I should tell the girl im ''dating'' now that I am not really loving her even though I said I loved her too.
<bot>: Broke up with my ex, can't forget her and I hooked up with a girl I don't have any feelings for even though I said I loved her too.
