Sorry you are going through this:(. I just have to say that you don't sound needy at all to me. Truth is, we are meant to live with our partners and share our lives with them, and for whatever reason, that is not happening with you right now. So, I don't know what your plans are or when you intend on getting married, but I would say, in the meantime, try to keep busy, build your own social support group, if possible. Keep eyes on the prize, and keep busy. Very important.
He sounds a little selfish, rather than you sounding needy. What happens when your little girl gets here? Is he going to be out drinking with the boys all the time or home taking care of his responsibilities? I hope it's just him trying to get it all out of his system before the baby gets here. I would calmly and rationaly explain how you feel to him and see if maybe he is just not thinking. Sometimes, we think guys think things through like women do, and that's just not the case, lol. Men's minds are much simpler than ours and they often don't think of the ramifications of their actions. Just have a heart to heart with him and ask him to stay home with you sometimes.
