First timer - baby daddy advice

Hi folks. This is my first pregnancy & I am super excited to be a mama! I feel confident and I feel ready but my main fear...the state of my baby daddy. First I'll say that I do see great dad potential in him. We have a solid plan for the upcoming months, but are admittedly not in clear waters as far as finances go, and he has struggled with depression and anxiety in the past. I'm posting because I'm not sure if his concerns are normal for a first time father. Is he over thinking the plans we've made to prepare for baby? Am I being overly sensitive? Are his struggles going to continue to weigh on me (and the baby) during those first precious and delicate months after baby is born? These are some examples of concerns he's bringing up with me on a frustratingly regular basis.

"It's not fair that you have more power here-it's my kid, too" "Are you sure you want to do this with me?" "If you think we might eventually break up, I hope you decide to have an abortion." "I don't think I'm emotionally ready to do this." "I just don't know what to do, I wish I could be stronger for you. What can I do?"

I feel helpless and exhausted when my guy approaches me with the same negativity day in and day out. Am I being too dismissive of his concerns? I just had my first ultrasound and loved seeing my tiny baby. Along with that joy comes fear I'll be tasked with nursing the baby...and baby's dad. I don't know if I can handle that. Have other fathers been afraid, but turned it around as baby grows, arrives and thrives?
