Hey all

(Just an FYI before I start...I am 26 and he is 31)
So I met up with my ex at the weekend...we haven't seen each other for about 4 years since we broke up (we broke up because I was young and pretty immature about our relationship before). When we saw each other it was awesome, we chatted as if we had never stopped seeing each other, hung out for the day and then I dropped him off at his house. He kissed me when we got in the car and I reciprocated...it was really nice actually
Anyway, so we spoke yesterday and just
said we should take it slow, meet up in a couple of weeks or so (we are both busy this weekend) and just see what happens. I am all for that,
I don't want to rush into it like I did before. However, he has an art exhibition on Friday and it is only 20 minutes out of the way of where I am heading for the weekend. I wondered if it would be a nice gesture to surprise him by turning up, only for an hour or so, just to see his work and show my support? I am just really worried about seeming too keen...
Thanks!
