Need advice!!

Well me and my boyfriend has been together going on 4 years next month. Well i see everyone around me getting engaged and planning there weddings and they have only been together half the time we have but my boyfriend said he isnt ready, and dont get me wrong i dont wanna rush him but sometimes i feel like its me and i keep bugging him about it and i feel like an ass for keep bringing it up but i wanna be married or at least engaged. Am i an ass?
