there's 22 years between me an DP!!
I am 23 and he is 45!! We havn't really had any negative comments (not to our face anyway) we do get some weird looks in public, coz we look like father and daughter i guess! haha! I really don't care! They don't know us or our situation! Both of our families have been really supportive even his kids, (2 of which are older than me). I think the only one who hasn't been is his ex, but i couldn't care less about her!! As many pp have said we don't even notice the age gap when we are together! We love each other and are very happy together which is all that matters!!
It's sad about your friends!! I lost my friends as well but it was before i got with dp. (bad breakup with ex and friends took sides! decided that they weren't really my friends so i think good riddance) but it still does hurt when you lose good friends! I can sympathise with you on that one!
