My 16 year old son has a girlfriend he has been dating for 3 monthes and I don't like her at all.Rude and selfish to me.Disrespectful to me and makes fun of me because I am in a wheelchair paralyzed from the waste down,was shot in the back 2 years ago which the bullet went in my spine.I hate it when she calls me "no walk" laughing at me.I am fed up what she is doing to me.My son knows some what is happening between us.I plan on having a talk with him on this.I don't want to hurt his feelings in a bad way and do it right.How should I do it so it's not done in a bad way?
