Someone is harassing my girlfriend. I want to send a text message to warn you. How to send this short message?

First of all, you have to find out whether you can beat each other. Secondly, I don't think it's necessary to send text messages, because if this girl loves you, no matter how many people harass her, nothing will change. If he is robbed by others this time, let you see the girl earlier so as not to be sad later. If you have to warn each other, you can tell him that your girlfriend loves you very much and we cherish this relationship. So please don't disturb our life any more. If they are friends, we all sincerely welcome them. If we're here to ruin our relationship, it will be really unpleasant.
