How do I

How do I calm the hell down about wanting to get married & have a house to live in & decorate & have babies?! My SO is still in college & living the broke college kid life other wise we'd be married already. I'm finished with school & have a job making good money & I feel like I'm waiting for the next phase of my life to start. I can't wait to officially start our lives together & love him so so much. I just get overwhelmingly excited & don't know how to calm it down lol does this happen to anyone else?
