You're in love and you're calling for help?? Ha! Age shouldn't matter. If you love her, then you love her. No stopping it, dude. My parents are 11 years apart by age, so it's not that abnormal...
No, she is a grown woman and mature enough to have a serious relationship with you. (or should be) If she was 16 I'd be telling you to seek professional help...HAHAHA Don't worry Tim...Carry on and ENJOY......HAHAHAHAHAHA
