Your guilt is a natural response to the situation. You care about him and are emotionally involved. But, what you did makes sense given the issues you've described from refusal to honor your space, lying about past marriage and inability to support you.
You're pregnant and a part of the guilt may revolve around you worrying about the child's future w/o a stable father figure. What you feel is a response to your internal dialog (what you think and what you believe) You feel bad about this happening because it is quite stressful and disappointing situation. There may be pent up hopelessness if you're realizing that he can't or is not willing to do certain things that you need/expect of him.
I am trying to give him the benrfit of doubt. I told him if could get his self together I might take him which includes getting a full time job, a divorce and taking care of his tickets. I guess I said this more to ease my conscious and his. Do you think this is actually workable I did not give a time frame which I probably should. Honestly, I dont plan on puting my life on hold except for now because I am pregnant. What do you think?
It is workable only if he is willing to work on himself and takes the initiative.
You are giving him a chance and he can decide what to do about it. If he does not improve, then at least you've been fair and let him know what your expectations of a partner are. Don't put your life on hold for others. If you do, do it for yourself.
