Much Needed Advice!!!!

So, I am 20 years old and I met my boyfriend (now 21) about 7/8 months ago. He is in the Army as is my dad.

My boyfriend asked me to go home to Florida with him to meet his family about 6 months into our relationship and I go for about a week. His parents absolutely adore me and my boyfriend shown me his piece of land that he's going to build a house on, etc. and gives me a promise ring. I told my dad and he freaked out because he didn't ask permission to give me a promise ring and that he felt we were going way to fast. I don't really give my dad details about my relationship because my dad tends to be emotionally abusive. I love this boy so incredibly much and I've never felt so at home before with him and his family in my entire life. They remind me of my own family and are very genuine people. Ive prayed and prayed for a man like him and I truly feel that god sent him to me.

Well, He just asked me to move to Florida when he gets out in June of this year. I haven't told my dad because he's very harsh and will make me refinance my vehicle (dad and step mom consigned) which is impossible because of my credit due to student debt and a couple of other significant things that I can't control. His mom and dad have a rental house that will be ready for whenever I decide to move and they will help me get on my feet so I would have a stable living place and get me set up for school whenever I decide to go.

I've had absolutely no doubt about my boyfriend for as long as we've been together. I'm finally doing what my heart tells me to do but I'm scared. Do you think its too soon for me to move?
