DID SHE REALLY!!!!!!!

I have a 14 year old daughter I periodically go through her phone after I saw a picture of her having a boy in my home. We had a long discussion about respect and her not having any boy in our home if I’m not there. I have to work and I feel like at 14 she should be able to be responsible enough to not need a babysitter. I mean there are no after school programs or anything for 14 and older. So I checked her phone again and there is another recent picture of another boy she has snuck into our home. I’m so over it and I don’t know how to handle it. Of course no more phone and her being grounded. I really need help on how to further handle this situation. 😭😭 Any thoughts please!!! it would be greatly appreciated.
