Hello, I have a serious question. I have been dating a male for about 11 months now. We live together as well, we have been living together for 3 months and before that I stayed over on the weekends. I have decided I no longer want to be with this male due to the way he treats me. Its nothing bad, just the way he talks and acts towards me nothing violent. The only issue is I am afraid for my 3 year old son who knows him. We tuck my son in at night together, and do lots of family stuff. I dont want to leave the relationship because I am afraid I will hurt my son. But I know this wont last through a marriage. help? What kind of effects might this have on my son? What can I do to help?

note: My son is only mine, his real father is not in the picture.

I thank you guys in advance for help.
