Leave the girls alone, and fill the void with activities that make you happy. By my reckoning, its been 3 months, after the 3 month relationship ended.
Frankly speaking, you are much too carried away by feelings, because you want the good, but haven't coped with the bad. Life doesn't work that way, you ave to deal with both good, and bad, and keep moving forward.
If you don't... you get stuck... and start drowning in your own crap!
