3.5 years and still waiting 💍

So BF and I have been together 3.5 years. 6 months in he told me he wanted to marry me and even asked me for my ring size several times. After a year or so goes by I casually mention it and he says he doesn’t have the money for a good ring. I really don’t care about the ring as long as it’s pretty. I found some on websites that were pretty cheap that I would love. He wants to spend at least a thousand he said so I say ok. I know he didn’t have a lot of extra money after his bills and child support and just thought it would eventually happen. He basically lives at my house and pays for everything at his house while it sits empty.

I then find that he has spent $5000 in the last 6 months on a couple games on his phone. I’m furious and so hurt. He knows that marriage is important to me but I feel like he has no motivation to get anything accomplished. I feel like if we were a priority together, then a lot of that money would be spent on keeping us together, such as engagement, fixing up and selling his house, even saving for his future. I feel so deflated and don’t want to waste my time if he’s complacent and comfortable, but also feel like we have a good relationship. So confused!
