<human>: Give me a shortened version of the text

My boyfriend and I (female) have been dating since January 26, 2012 (almost 3 years). I am 22 and he is almost 24. We moved in together in June 2014 after I graduated college. He is in grad school now working towards his PhD, which will take another 5 years or so. I went to a Christian college where I saw a lot of people get engaged, married, and in 1 instance, have a kid while still in school. I know this is not the norm, but all I see on facebook is people getting engaged. It really upsets me when I see that they have been dating less than my boyfriend and I have. My boyfriend just tells me not to compare our relationships, but I can't help it. My brother is getting married to his finance and they have been together for 7 years (ages 23 & 24), but I am so happy for them.

We do have problems in our relationship (me not happy at work, taking my anger out on him, etc), but he knows I want to get married. He does too, but doesn't want to rush it. I know getting married won't change much because we're already living together, but I want it now! I don't want to give him an ultimatum like some people have told me to do, but I don't want to wait another 5 years, either. He said he would have no problem getting engaged and maybe married while still in school, but I don't know what he is thinking time-wise. I ask him "will we be engaged in less than 3 years," and he can't give me an answer. I know he doesn't want to ruin any surprise and tell me when it'll be and I don't want that either.

I don't really know if I'm asking for advice, or just someone to vent to. Please don't respond in saying that I'm being immature or to just get over it. It's hard enough seeing people on FB get engaged after dating for 4 months (true story...). Thanks!
<bot>: Have been dating for 3 years, when is my turn to get engaged. Sick of seeing people get engaged when dating less than us.
