Feeling Jealous of Ex's Engagement

I agree with the others here.. the fact that you’re jealous of the ex just indicates that you want that for yourself and you don’t feel like your current partner is quite ready for it. Communication is KEY trust me. I’ve been with my guy 7 years.. we’ve lived in a variety of places and still haven’t managed to kill each other yet because we talk about stuff like this! I wish you the best! Just make sure you’re clear and that you feel heard and loved 🤗

If you haven't already I think you need to ask him very directly if he would consider marriage at any point IN THE FUTURE. Given that he "doesn't care" if he's married or not, would he consider it given its importance to you? if you haven't been having honest and open conversations about it, then you won't know your options. It's also possible he doesn't want to ever get married and honestly that's valid. I personally think no one should feel pressured to before they feel ready, regardless of children / length of relationship because then people become miserable and feel trapped. You chose to settle down with someone who has expressed indifference to marriage. Maybe it's time to consider how you would feel if he was never willing to get married. Would it be a deal breaker? Would you want to pursue a relationship with someone else who is interested in marriage? Or would you rather be with him even if it means not ever getting married?

Have you tried expressing this to him or maybe proposing to him first? It could be about finances, that's he's mentally not ready for that commitment. He might not even think too much about the whole situation. I know a lot of people who don't want to get married... Maybe you two could have a sit down and talk about it?
