So maybe you think she is moving to fast? Many people move very quickly into a new relationship, I have several friends that did, and years later still together. Either way its good she is happy, and experiencing life instead of depression. So I say YAY MONARC!
I split with my ex in May (give or take, lol), then dated around (nothing serious) and then by the end of September I was already living with another man. Only started talking to him at the very end of July, went on our first date August 5th. We already figure on getting married. I already love the man. Judge not. You don't know what is going on, and nobody really has any room/right to judge.
