I had my rebound too. I met him when my barely a year old daughter was away for a weekend with my ex and his AP, 6 months into the separation. I was in so much pain, out with friends, and this incredibly hot guy is talking to .....ME! A friend of a friend I was with (whom I can't stand was hitting on him, but he wanted ME!). Long story short, we dated for 2 months. The feelings I got with him were so amazing (never thought it was love) but anything compared to the pain I was felt heavenly. When he broke up with me to date someone else, I so didn't want it to happen. Because of the feelings I had when I was with him. Not because of him. because I could escape the pain, I felt beautiful, sleeping next to another (hot, might I add) body. I didn't want that to go away.
When we ended, just like Cadence, it was my ex I cried for, not him.
You are going to do what you are going to do. But please, pull back the love reins here. If you are going to enjoy it, enjoy it for what it really is in this moment.... a rebound. Maybe in the future it won't be, who knows. But this R is painting the way you view everything else, and right now you need to see clearly to sort out your feelings for yourself.
