Beautiful ladies! I need your advice please

Okay so let me get straight to the point...

So I've known this guy for 4 years. He lives an hour away from me. I've seen him in person, we know how we look. He initially started messaging me on social media. He is my friend and we give each other advice about literally everything. BUT about a year ago or so, we began to sext. He usually always wants to start a heated conversation and I will admit I give in and sometimes I feel like that's all he wants now. Plus, he only directs messages on social media even when he has a cell phone. and what hurt more, he asked me phone numbers of two girls, it hurt a lot. Even though I am his friend, I would at least think he would want me in his contacts. I feel I Am I just an object to him, not valued just a hidden secret?

Please ladies, tell me your thoughts on this situation. Would mean A LOT.
