Confused I am new

My name is Krissy and I am going to be a mother come february. My boyfriend of three years and I found out we were expecting a few months ago. At first he was, I guess supportive. But now he brings up adoption all the time. I am a 24 year old, college graduate with a very good job. Financially, I can do this on my own. But we have decided to go our seperate ways. Seperate meaning I am raising this baby on my own and he is...well gone. The last I heard, he wants to terminate his rights to the child. Any advice for these last three months and the next 18+ years to come would be appreciated. I am excited about being a mother...but sad she won't have a father. Anyway...thanks for listening and I look forward to the advice.
