feeling confined

so I had my baby 3 weeks ago and the dad and I aren't together, he has come about 7 days in total to visit her. otherwise she has been in my care in my home since day one. ( because he has no home no job )so lately I've been feeling so alone just me and baby I miss being able to do what I want when I want . I've took her for a walk with me in the stroller once and other than that I haven't left the house for more than a few minutes to get groceries. I asked if he could come over to watch her tomorrow because I'm so depressed being inside all the time.. alone and he's fighting with me all the time i just want to go out and visit some friends. does this make me a bad person or is this reasonable?
