Am I over reacting?

I have been dating my boyfriend for over 6 years. I try not to get upset when I see other people getting engaged before me, but it’s hard. I asked my boyfriend yesterday why he hasn’t yet and he said I didn’t know. I got very upset with him because I feel like we are at the point we should be getting engaged. We have lived together for over 2 years. I just don’t know what to do. I truly love him, but this was really hard hearing yesterday.
