He said he won't propose until a major life altering event happens?

My boyfriend (32m) and I (28f) have been dating for 2 years now. He and I have discussed the topic of marriage. We both want to get married and he has said he already sees me as a wife and that he is excited about that. He has also said that our relationship is the healthiest he's ever been in and that he has thought of ways to propose. His friends and family also believe we are going to get married. Having said that. Sometimes he says things that contradict all of this. He will say, I don't want to propose at the wrong time, I'll do it if you want me to but it's not necessary, and the last one was he would consider proposing if a major life altering event happened, but he's not in a rush. So, I ask. What gives? Has he been lying to me?
