Ppls judgemental opinions on marriage

I've been in a relationship with my man for two years (may 20 is our anniversary) he also joined the army last October. We don't want to get engaged or married. We have no reason to really. Already have same last name and both will be in the army soon. Anyways everyone has given this break it off now or get married now attitude. Like tf this isn't ur relationship to say anything about. I don't but in about who u married or ur SO or tell u how I would parent ur kids. Don't tell me what I should do with my SO. What's ur ladies views on this.
