How to tell my parents...?

I have a feeling you are going to be getting a lot of reactions to this post. That being said...what's the rush? It's great he can support you while you go to school, but you will be entirely reliant on him, and trust me that is not a good feeling. If it were me, I would wait until I could pull my own weight, otherwise if this goes south what will you do? It's his place, he pays for it, you have no income, where will you go? From what you have said about your parents it doesn't sound like they will come to your rescue. If you are dead set on going through with this I would wait until after the holidays, and do it in person. You likely won't get a great reaction, and you need to be prepared for them to pull their financial support.

First off, you’re an adult. If you’re dating, you need to be adult enough to tell your parents. You’re reliant on your parents currently, and willing to sever ties with them to become reliant on a person you’ve known for 3months??? You’ve not had a chance to be an independent adult. I don’t say that to be mean, i say that to be honest. You really need to stand on your own, experience being an independent adult before marrying. Giving up your “freedom” and independence for another person so quickly is honestly concerning. This is scary, my parents wouldn’t be happy with this at all. Have they even met him?? The fact that he’s rushing is odd. Also why are you so content with being completely dependent on him?

I couldn’t,don’t imagine severing my relationship with my parents for someone I barely know.

Don't do this. I was head over heels in love at 20, and had way more fun single at 21. I needed to grow independently and so did my FH we started dating when I was 18, and we broke up when I was 19. 19-21 were my crazy, fun, bad reputation fun years. I have had a job through all of this, and my parents let me live with them while going to college, and living rent free was lovely. You should wait. 20 years old is too young IMO. I think you need to live with this guy, get to know him better, and see after a few months what this guy is about. I've been in love, but the guys were just so in love with themselves, and I was constantly disappointed. Date through the rest of college, and bring him around your family. It's not bad to be in a relationship with someone and see the world. Date the guy for a year and then reevaluate this. Marriage is forever, (supposed to be anyway!) Don't rush it.

The day I started dating my FH, we were head over heels for each other and started planning our wedding. Here we are nearly two years later and we still feel the same way, and don't feel rushed to get to the altar. I understand the feeling, I'm your age exactly, but sacrificing your relationship with your family isn't worth it. It's okay to tell them that you're dating, and that you're pretty sure you'll end up marrying him. Don't risk cutting them out of your life by rushing into a marriage.'

ETA: I see your relationship with your family isn't too great. That really sucks, and I'm sorry. I'd still advise you to wait. My FH's parents told us that they were fine with us getting married as long as we waited until after we graduated. I'd tell you to wait until you graduate too, or at least wait for another year. There are some things you just can't learn about a person in three months.

So your parents house you, feed you, give you a car to drive, a phone to use and you want to turn your back on that so that a man you've known for 3 months can house you, feed you, give you a car to drive, and a phone to use? Are you capable of doing these things for yourself?? I'm a firm believer that until you can stand independently on your own two feet, you have no business getting married.

Also, your parents are controlling because you've given them full of control.
