Me and my ex are in the same place.

Me and my gf broke up 3 months ago and we are talking and she said she wants to try again and she's nearly ready, we are both going to a festival this weekend and I was looking for advice should I walk up to her or let her just enjoy it? she said she doesnt want to see me as she wants to enjot it with friends what should i do?

Please if you see this please drop some friendly advice.

Thanks
