HI Jessica! Sounds like you have your hands full! And you know your hormones are raging full force right now, so I'm sure that doesn't help either... But here's the thing. You shouldn't have to worry about "chasing away" a man right now. You have a little girl to think about, and you have to think about what's best for her. You have to think about the kind of relationship you want to show her, which should be the kind of relationship you want her to have. Think about it this way: Fast forward 20 plus years. What would you tell your daughter? Would you tell her to stick it out with this guy? Or would you tell her to be strong and if the man wants in her life, he's gotta be ALL IN. Not just some, and not wishy-washy either. Having him there half-way is probably worse than just knowing for sure one way or the other. What if you thought you could count on him, say to give you a ride to the doctor one day? And he didn't show up? Wouldn't you rather just know one way or another?
But of course, really the bottom line is that this is your relationship, and only you know the right thing for you to do. You just need to do what feels right- for you AND your baby. GOOD LUCK! And remember, you are a strong and capable woman, and YOU CAN DO IT!!!
