Sex doesn't fix things, open and honest communications helps fix things.
It sounds to me that your ex feels as though you valued your male friends more than him and it also seems that his head is at a cross roads between you and his ex. Now it wouldn't surprise me if this dude never stopped caring or having feelings with his ex and has conveniently used your guy friends as an escape mechanism. You mentioned that him and ex were each other's firsts and that means that he has a stronger bond with her than you and if given a choice he's more than likely going to choose her over you.
It sounds to me as though your second best and I am sure should things not work out for him and his ex that he will back with his tail between his legs asking you for a second chance. It's up to you whether or not you want to be second best. If you don't mind wait in the wings for him, but I certainly wouldn't in your position and next time you are with a man, don't make him feel inferior to your male friends that's just lame.

You have openly admitted the break up was all your doing, Lorandy, and with this being said, he still chose to be in your life because he is missing the kissing and all the things you both shared as a couple.
However, with him being Out there now, you may have chased him back into the arms of Her again and this has led him down the road rage To------He's confused.
This now what I call a Triangle Threesome, where you are at the tip, looking down, from side to side at the both of them, sweetie. Having friends with benefits, which you are basically doing now, should stop or it will only add fuel to the fire and someone is going to end up getting burnt.
You have made some mistakes and during your time together, no compromise was made, you compared him to others and now this is headed down a beaten path that could very well end up to be War of the roses.
He is leaning on her once more because he feels he can count on her when the chips are down. With you both broke up now, still having full circle patterns, this is what it has led to and there may be no way to 'Fix things.'
All you can do in this point in time, is hang in there, show him you are different, don't compare him to all the tom, dicks and harrys and show him he is the one you really love... you might want to also rearrange a few of your guy friends so this isn't also an obstacle that gets in the way.
I don't know about her sign 'Libra' so much, but there are definite 'Signs' here that this is not over and there is going to be more in store behind closed doors.
Good luck. xx
