I don’t know what to do

I have begged and obsessed over getting married and having a family but I’ve finally realized that my boyfriend may not have the same goals. He finally agreed to trying for a kid about 2.5 months ago(after 2 years together) but it was after him feeling guilty for staying out late. He said he felt like he had been being selfish and wanted to do something I wanted. He has not expressed any interest in the process and he gets irritated whenever I mention marriage because he says I’ve mentioned it too much. He always says he has things he has to do before he marries someone but he hasn’t done these things or even tried to. Am I overreacting or is he under reacting
