Edit: The below is true for (most states in) the US, which I have assumed OP is from based on the use of "mom" and "OWI". The downvoters are ignorant.

If you're an adult then legally you're a tenant, and you have all the rights of a tenant living with a landlord. Given that you almost certainly don't have a written contract, there aren't really any additional terms she can impose that go beyond a standard tenancy agreement.

To be clear, most jurisdictions treat a tenant living with a landlord slightly different to a tenant living privately in a separate property. So if you want to look up your rights for where you live you need to make sure it's for that kind of cohabiting situation.

However, your mom can't just kick you out, legally. She has to formally evict you using the same process any other landlord would evict their tenant. If she did kick you out or change the locks, you would be within your rights to call the police and have them mediate to grant access to your home.

As a tenant, you are allowed to have guests over. Not just waiting outside or on the driveway to pick you up, but inside and maybe even occasional overnight stays. Although again this may be where living with the landlord makes it slightly different.

All of this is underscored by the non-legal parts - your relationship with your mother and your continued tenancy. She can evict you, and if you fall out then she may well do that. Just because the law is on your side doesn't necessarily mean your mom will want or have to maintain a relationship with you. A balanced position might be to assert your rights while trying not to be a dick about it and offering a fair compromise with your mom. I would say meeting your boyfriend in your driveway is a reasonable compromise, however she might not see it that way.

So first of all, your mom is reluctant in letting others know where she lives. It has nothing to do with rights but with decency and respecting her wishes.

As when it comes to your rights, actually you have very little as an adult. Technically now your mom could say that you have to move out and if she did that you would be on your own even if that would mean being homeless.

Since you are so eager to go on a date, asking about your rights wrt your mom I think you likely don't understand why your mom is concerned and sound like an easy prey to someone that can just use you and you will deeply regret shortly after.

Why not meet someone in normal circumstances (like school, work etc) instead dating strangers?

Remember that having additional privileges is a small part of being adult, much bigger are responsibilities that you get and consequences of bad decisions that you make.

Don't start your adult life with something you might regret.

It's funny that kids wish they were adults while adults wish they were kids again.
