Too soon?

My BF is a wonderful man and I love him with all my heart. We have known each other for 5 years as really good friends and have only been dating for about 5 months. Recently he has unofficially asked me to marry him and I said yes.

But now that a few weeks have passed I have really began to think about our situation.

♢He was discharged from the Marines last August and not long after he broke his wrist so he has not been able to get a job. He does get a military check once a month.

♢I just left my job due to major sexual harassment at work.

♢We live with his Grandpa .

♢We both want to go to school, but im worried that we can't go at the same time, because of our financial situation.

Bottom line- I love him, I do want to marry him.. am I overthinking our situation?

I really don't know what to do at this point.

What would you do?
