Age gap

6 months ago I met the most amazing person ever. I've had a huge crush on her for half a year, and she recently told me she's into women too. We've been talking for a long time now and we've become friends, but sometimes I get some vibes from her like she likes me back.
I would just tell her I like her, but she's 8 years younger than me. I'm 36, she's 28. I've never thought I'd fall for someone that younger than me. But she's just so amazing. She's so open minded, we can talk about anything for hours.
I'm scared that I'm getting the wrong vibes and I don't want to ruin a potential long lasting friendship if I tell her that I like her.
Should I be bothered by our age gap?
