What do you think about this?

So backstory, I’ve been with my boyfriend for 2 years and we have a 4 month old together and my 5 year old is like his own child too. He knows that getting married is very important to me and he’s said stuff like we’re taking it slow, that he wants to save up and get me a nice ring. Even though Ive told me that all I want is to be married to him and that I don’t care about the ring or a big wedding. I would be way too happy even with a Walmart ring and a small party or even no party at all. a few days ago three of my closest friends got engaged, and I was just telling him about it but he didn’t seem to interested in what I was saying.

One of them got asked in front of everyone in a really big concert. I was telling him how cool that was and showed him the video, all he said was well thats a dumb way to do it. That same night we went out to a bar and we saw a bridal party there. All I said was a lot of people are getting married and he seemed bugged by my comment which by the way I didn’t mean it to be passive aggressive, I just meant that a lot of people were getting married haha And he went on about how I save more money than him and that he has a lot of bills and that I don’t and about how he owes the government some money for a benefit he deserved when he was in the Air force but was getting paid way too much for it and he didn’t say anything about it and now has to pay back. He made a Comment about how I don’t want to marry him because that would be my debt too. I just stood there speechless

He pays bills and rent. When he was asking me to move in with him he said I didn’t have to pay anything but the groceries. I don’t even make half of what he makes in a paycheck and I pay for the kids daycare, my car, my insurance, phone, groceries and everything else the girls need also Im going to school for social workewhich I pay for put of my pocket and I never ask him for money because I feel like he already pays enough. I just feel like he keeps coming up with excuses to avoid talking about it. I just need to see other people’s perspective on it. Idk if I should just let it go or keep pushing it or what. I don’t know what our plan is for the future or what he wants to do and it gives me anxiety. Ugh 😫
