This guy sounds familiar to me, so I would suggest that for the time being, you go stay with your mother and then go on with whatever plans you would pursue if there was not a guy in the picture, i.e., whether or not you work or work part-time, assuming your Mom will be helping you initially with child-care. Talk to your Mom and tell her that the father will definitely have visits with the baby (but not in the wee hours after a wedding, and reeking of alcohol!)--at reasonable, non-disruptive hours. And that you will be seeing him, sort of having "date nights" until you work this situation out between the two of you--either marriage or continuing living apart with his being allowed time with the baby. I don't really know your situation, but I would strongly suggest NOT marrying the guy right now, at least not until you see more sensitivity and fairness coming into play from him. Why? Because if it's bad now between you (i.e., no sensitivity), it will be far worse when he considers that you "belong to him." So...slow, steady, thoughtful actions are required now, for you and for the baby. If you have the option of living with your Mom, assuming she and you have a good relationship and that she understands that you will be involved with the man, to some degree personally, still trying to decide what to do marriagewise--then the baby will at least have consistency and good care, and you will have peace of mind, knowing you are in charge of your decisions for both yourself and the baby. It might be that you will find that this man is not the person you want to spend the rest of your life with, but that he can be a part of the baby's life, at least for awhile. Good luck. You sound like an intelligent, reasonable, sensitive lady, who wants the best for her baby. And kudos to your Mom, too! I hope it works out well for you and your little one. P.S. There is also the option of making your Mom LEGALLY the child's guardian, since you are not actually married, in the event you were not able to raise him. I.e., he needs some legal documentation as to who would be your successor as to his care. And secondly, TAKE OUT A LIFE INSURANCE POLICY NOW for him, in case you should die. Very unlikely, but the policy will not cost much and will give you peace of mind as to his care in the event you are not there. Do this today!

P.S. to my post...the Life Insurance Policy I mentioned would be for YOUR life, not his, as my post indicated--it would be for his benefit if you were not around.
