It is in your words, right there. You need a girlfriend who does not have young children to take care  of and who  has enough money and time to have fun activities with you, trips on weekends and such.

Keeping it  simple, you don’t want  to be a dad or a caretaker to young children. You want to have fun with a woman who does not have young  children and who is able to do fun things in weekends with you. When you have a girlfriend  like this, who is of course nice to you, affectionate, then you will forget all about your ex again, just like you did before, don’t  you think?

I totally agree with Anita. It seems like this to me too. This is the sort of relationship that truly seems to make you happy.
