Of course you feel stuck...unfortunately in this particular circumstance the cart was put before the horse. If you stay with him or if you decide to go on with life without baby's daddy, you really need to work on you.
If I planted a seed in the ground, waited two days and then dug it up to see if it were growing. It could never grown like that.This is pretty much what you have done here. It is wonderful that you now want to take the time to get to know him but you have already given up so much to this man and why? (Rhetorical question.)
The true question here is if this is a salvagable situation or even better question, what would be in the best interest of your son. Children learn by what is taught and what is caught. How much respect does this man have for you? How much respect and love do you have for you. Real love requires respect. Respect isn't a thing that can be demanded of anyother but commanded of another. If I want someone to respect me I don't let them treat me disrespectfully.
Why did you think it was a good idea for you to give up your job, car, lifestyle to move into a stranger's world? (Once again rhetorical question.) I don't need answers to these questions I'm asking you but I think that as you begin to answer these questions for yourself, it may lead you to make better decisions about what direction you want your future to go in.
He doesn't understand what is going on because he is perfectly fine with falling into be with someone in a short period of time and everything else that has transpired between the two of you. The thing with the car is just a conrolling and power move. Many mother's don't have cars but they make it work. It isn't easy but you do what you must as a mom. I really hope this post didn't hurt you but helps you. I'm wishing the best for you and your baby and his father understanding that the two of you together at this time might not be the best and it may take time to get there.
