Hockey player???

So my mom just got divorced and i want her to be happy and she’s been talking to this cute hockey player (one that i jokingly called my future husband like 2 years before she met him)

And she wants to ask him out and everyone is like hells yes do it and i want her to be happy but at the same time he is 25 and only 6 years older than me her oldest daughter

And i don’t normally care about age difference but for some reason i just feel really awkward about it and i feel like i don’t have a right to feel awkward about it because liek it’s what she wants i love my mom and i want her to be happy but i just i dunno
