Is our age gap too big?

Hi everyone!

So I have a new boyfriend and he makes me really happy, but he is older than me. I am afraid that my friends will find this unsettling and therefore I haven’t told them about him yet. I really want them to like him, because he has such a great personality and he is a big part of my life now. I am 17 and he is 22. Do you think it is too big of an age gap?

Hugs :)
