I've been trying hard not to reply in this thread, mostly because I feel a bit tainted on the issue.
In reality it doesn't matter what any of us say about it, but how you feel about it. You wouldn't be posting this if you didn't have some reservations about it. So what is holding you back?...is it just the age difference, and you are looking for 'approval' from others?
If that is all it is, you don't need our approval, if you want to see where it goes, by all means go for it! If you are holding back for some other reason...maybe a vibe you are getting or something, explore it because only you can make this choice and it is best if you know what you are getting into.
My experience is limited...but I found with a 6 year difference we were both in a very different place in our lives...love just didn't seem to be enough. Although the distance didn't help too.
Anyway, think about what is holding you back and see if it matters or not. Be safe, and good luck!!
