Bad Break up and I need some help

[AlaricXY]

Sorry to hear about your break up.
And no, you don't sound like a psycho. Telling that girl is the right thing to do preventing her to suffer the same fate like you now.
Stop wondering what's his actual sexual orientation. Forget him and move on. You are nobody's object of replaceable love. You are a prized possession.
Sad to see he can easily wipe off years of friendship and love with you from his mind, but it is obvious that he doesn't love you enough and take you for granted, use you to experiment for his wicked sexual confusion. Don't cry or feel sad over a man like him because it's not worth it.
Better to find out now that he doesn't truly love you while you are young than having him telling you that he loves you no more when you are 40.
All that youth wasted away.

Let go of him, why let a jerk like him causing unrest in your mind?
You sounded like a guy fond of love and appreciative of loyalty and commitment.
Guys would line up for you.
Your ex is just replaceable.

Lastly, if you really love him, let him go. If he loves you, he will come back for you. If he does not, it's just not meant to be.

You are just 30, not 50.
Go out and find a man who loves you just the way you are.
Not a guy who plays with your feelings and love.

Take it easy.
Good Luck.
