The only thing I can suggest is that rather than feel regret, appreciate the time you had together and take it as a learning experience. You can just as easily feel the way you did about that girl with another but this time you'll know where you went wrong.
Life's all about making choices and dealing with the consequences, but you learn from the mistakes you make and by doing so become a better person.
I'm sorry to hear that things didn't work out between you and your child's mother, though.
thanks man
Yeah, I guess maybe it's the loneliness kicking in. I've been on my own in this house since just after christmas. First time in 7 years this has happened.
