<human>: Summarize the given text in a few sentences.

Now, maybe I am wrong and he has been secretly saving money. But living together, and knowing everything that the other person buys all the time, I feel like he'll never have enough money for a ring. I know he's a guy who will want to spend the '3 months salary' and impress me with a gorgeous ring. But he keeps buying expensive things that we don't need! 
When I first met him, he said he wanted to be married within a year and have kids by 28. I was very against that, but now that almost 3 years have passed I'm getting anxious! It really hasn't helped that his 25 year old sister has just gotten engaged and as he said 'stole our thunder'. That has been pretty rough on me, seeing as they're a super close family and I feel that everything that his sister is talking about, planning, celebrating was supposed to be ours first. She's the type of girl who is always fashionably dressed, is the only girl so she gets all the attention she wants. I love her, but I can't help but feel this animosity towards her and her fiance. Not to mention before she was engaged we spoke about this a few times and she kept telling her fiance that he had to speak to her brother to make sure that their plans wouldn't interfere, which the fiance never did. I'm surrounded by a lot of weddings at work and I get so sad thinking about how I'm not engaged and not able to start planning our own celebration. She also is getting married in the same season that I would be getting married in if I got engaged in the next 4 months. So now I'm being told I'd have to wait an extra year....
<bot>: I want to get engaged but my boyfriends sister stole our thunder, and my boyfriend doesn't seem to have any money to propose anytime soon.
