So lost

My boyfriend and I have been together for over 2 years and we live together and I’m scared he’ll never commit because we moved in together. I initially moved in with him because we were both moving to the next stage of our lives and I figured he would propose at some point soon and living together would make the quick transition easy. Now I fear he’ll never propose. He never talks about actually doing it but often talks about our life and kids together one day. We have also been splitting the rent 50/50 and I guess I just always imagined I would move in with a man who had it figured out and would provide. I’m and engineer so by no means am I asking to be a stay at home gf lol I have a great job. It’s less about the money and more about the principle of seeing him as leader and a man. This has caused me to become unattracted to him and our lease is up for renewal and I’m not sure what to do. I love him deeply and he’s my world but I just don’t know anymore. I’ve brought this issue to him many times and I’m met with hostility and anger ( I’m thinking he’s just defense) and he also says that if he’s not the type of man I’m looking for then I should just leave. Am I wrong for asking for change? Should I leave? Will this ever change or should I take him up on his offer and pack my bags? PLEASEE HELP
