By therapy I mean therapy for yourself. Not couple. I’d focus on figuring out why is this pattern of having partners and friends who are so dismissive. You can’t fix these people but you could try to understand patterns in your life and.therapist could help

As about this boyfriend. If you don’t even know his future plans, I’d put marriage plans on hold. He is in a different country and now apparently not even working and he refuses to share his plans with you. Nothing in it spells planning marriage. Wouldn’t you like a relationship with a man who is clear and direct in his communication and his intentions?
