Mom problems...

Mikayla • 16, in a relationship with the loml
Does anyone else have a mom thats a little over bearing? Ive been dating the same guy for almost 8 months(hes 17, im 16) we're in a completely monogamous relationship, and having safe, consented sex which we both discussed for a long time before doing. However when my mom found out, she told to stop having sex with him or she'll ban me from seeing him. If she drives us somewhere, which is rare, then i have to sit in the front seat while hes in the backseat and if hes at my house then we're not allowed to sit near each other because its a "slap in the face to her" because we've been having sex. Im frustrated because shes so incessantly worried about this and makes my boyfriend and i feel belittled and like our relationship is shallow because of how childish shes acting towards our relationship.
