Men use empty promises as carrots to keep the benefits of being with a woman without the commitment of marriage. If you give him an ultimatum, the realtionship might end and you don't want to be single again, god forbid! But maybe he'll say 'ok' and you'll finally marry! Hmm... Are you sure it's a good idea to get married to a man who needs an ultimatum to become your husband??
If you keep trying to get that carrot, you're giving him the power to decide the fate of the relationship. Take back your power and get out of that trap!
I haven't seen other videos from this creator, but she seems to be wise. I'm going to check more of her stuff. It is so good to see more and more women speaking up and giving advice that aligns with FDS.
