honestly, at age 30, i wouldn't date someone who's 7 yr younger than me. my ex was 4 yrs younger than me, but i didnt' care because I wasn't serious.
And yes, the age gap matters. To me, if I'm dating a guy who's 7 yrs younger, i won't take him serious. I might like him a lot..physically, but wouldnt think of spending my life time with someone who's that much younger than me.
That's just me..
Circumstances or people can take away your material possessions, they can take away your money, and they can take away your health. But no one can ever take away our precious memories. So, don't forget to make time and take the opportunities to make memories everyday. To everything there is a season and a time for every purpose under heaven
