New- relationship-scared of losing bf

[Person66]

I'm 23 and I used to be str8 but not long ago I started becoming attracted to men too! So I guess I'm bi now? Well somehow I met this gorgeous guy (he once worked as a model :biggrin: and go-go boy but didn't like it) , a fellow student, who's a year younger, and now has a non-threatening job. He previously graduated from culinary school and makes my favorite foods without my even asking. I know I'm attractive but I'm no model we have fantastic sex and he treats me almost too good, often asking me to stay at his apartment very often.
They sayif it's sounds too good to be true it's not true That's how I feel about this relationship.
What"s going on here: a gorgeous hot guy wants to give me fantastic sex, have me over as much as possible, cook for me, give me little gifts, introduced me to all of his friends (we clicked) and generally dotes on me. He even sometimes talks about are relationship long-term.
Does this not sound too good to be true what did I do to deserve this?
I don't think I have as much to offer him. I'm not as goog looking, I can't cook, nor do I have my own place. It's going to take me longer to graduate as I am studying medicine, while he's studying engineering.
What happens when he finds someone hotter with more to offer? Or gets tired of treating me so good? He'll graduate and have a job as I still have a couple more years of school.
I'm so terrified he's going to leave me and I'm getting attached to him. I thought about just ending it now! But I just can't. My heart was already broken by a girl, it can't break again!
What do you think is going on?
What do I do?
Any opinions will be greatly appreciated.
