Well you learned from Joy some things and you need to take it with you...but dont think that because it happened once it will happen again...you have to give Betty a try here you have no reasons to distrust her right now-and remember the age diff too! Thats gonna say alot too. Dont stop dating because you had one bad experience in one area of dating. Be open and honest with her! Its up to you in what you want to share-and in your own time. You'll know when things are right to bring up or not.
But in the meantime Bono-take those chill pills buddy-its all good...remove the duct tape and go with your gut...relax and have fun!
