I think my girlfriend is closer to my daughters age
How does the age gap make you feel?
I don't like it and I think we should take a break for a while.
While it is wrong for adults to be in relationships with children, it does not mean that people cannot date others who are younger. As long as both people are adults then it is ok!
I know, I just wanted to vent my emotions.
That's alright, and it's quite healthy you are expressing them. While age can be a concern, if you love your girlfriend truly, then these can be overlooked.
