not at all. i had a boyfriend with 8 years differences. but what? nothing we can do with that. he's not even as mature as 18 years old and not as wise as his age. so i think age is just a number that can't guarantee his adult personality.
what do you mean by relationship? If you mean the relationship between the opposite sexes, usually the first thing that makes people bond is their FEELINGS, regardless of their age or even social satus, but with the passage of time people discover the differences, which could be troublesome at times. and certainly big age difference could be troublesome
Depends. Sometimes it's not but sometimes it is. I don't think age matters but sometimes people of different ages have different interest and points of views so the relationships don't work.
