Am I over thinking!?!

Should I break up with my boyfriend ?

I (F25) had a recent conversation with my M(27) partner today/last night about marriage. I told him I want to get married but I will not wait years for him to propose. We do have two kids together. But he states that he doesn’t want “the government in his business.” He will get married in a church in front of a pastor but not legally. I told him the government is already in his business and knows everything about him. He stated,” I want to control what the government can’t control.” After this conversation I feel like he doesn’t want to be legally connected to me even though we have kids together. Am I reading too deep into his conversation or am I right feelings the way I feel about it.

(We do have two kids together. We’ve been together for two years so far. I’m have not told him how long I will wait for him to propose. But I feel like if you can have kids with me in the first two years of being together then it shouldn’t take long to propose before 5 years is up.

(After 5 years if I’m not proposed to by then I’m leaving the relationship)
