You are 23, she is 18. Both of age , so that is not a problem. But you are both at different places. She is just coming out of her teens ! I do not know either of you. You may be in different places in your lives. On the other hand , it may work out !
It depends on where you are at in life, whether your looking to have fun or have a serious relationship. If your in college and she is in highschool, then I think it's an issue, but if she's in college then there's not a big problem.
We agreed (beyond remembering) to descend the long spiral into density to cocreate with the Supreme Creator and through Faith, ascend the Eternal spiral upwards through & into Love, Beauty, Truth & Harmony Amen
