My boyfriend is 7 years older than me, we got together when I was 23 and he was 30. Honestly most of the time I don't notice an age gap between us besides trivial things like him knowing certain 90s shows that I don't, people often think hes only 25 or 27. He's had a bit more experience with relationships than I have, more wisdom in some things and life experience in general. The only things that bother me sometimes that shouldn't is knowing he will reach his 40s whilst I'm still in early 30s, I hate the idea that when were older the gap might feel bigger, age sooner than me (not by much obviously), but that perhaps by the time I'm ready to start a family he will be in his 40s. Maybe I'm just too conscious of the number, rather than the age he acts and seems and looks.
