Last year the relationship between me and the mother of my 2 year old son and she asked me to leave. We had been together for nine years. After 5 months apart I met another women, with whom I have fallen in love with. She has her own son. I see my son 2 times a week and he usually stays one night a week. The problem is I feel so guilty spending more time with my girlfriends son than my own. Ny ex has also made it clear she wants me back. Its given me such a dilemma. On one hand I love my girlfriend so much. On the other Im not sure if I can go on playing happy families with my adopted family.
