How old are you two? If you want my advice it is your going to both have to act alot older than you are right now because your baby needs you. When your older your going to look back and you will remember the quiet moments you spent at home as a family watching your child learn to crawl, walk or just laughing at the crazy cute things they do everday. You will not look back and remember wow all those Friday nights out at the bar were a lot of fun.
You three should be doing things as a family. Take your child to a playgroup, or the playground, or the zoo. I used to take my son to the pet store when he was real young. Its free and they love to look at the animals.
This is just my opinion. I do not know your whole situation. I have a 2 1/2 year old son and my wife works nights, so we do not have the easiest life right now. But we make the best of it.
