My aquarius boyfriend keeps breaking up with me...?

Aquarius men don't know what they want. Yes, they fall in love, but they also feel suffocated after a while and need to feel free. Get firm with your Aquarius. Let him know you love him but that you can't keep doing this. If he wants to be with you, then he can have space, but he can't keep running away and hurting you. Make him understand (if it's possible) that relationships don't have to be restrictice. And if he's not ready yet for a serious commitment, let him go for a while, but don't take him back until he is good and ready. It won't feel good to have him run in and out forever.
