Is it better to be single with a huge bank balance or married and having palpitations due to financial worries?

My boyfriend moved his stuff into my house but then left to work overseas and has been there for 12 months. Will he come back as I have all his stuff?
How will our relationship last like this? My boyfriend of 6 years, his family have no interaction with my family. He doesn't like my friends and I am not keen on his friends. He also wants children and I don't.
Why do I still feel like I’m in pain? After breaking up with my long distance boyfriend only to get back together 3 days later.
