I feel like this is a bad piece of information for me to have because what if I abuse it and start to over text/call him and it gets out of control? I dont think I will use it when I am ok but when things are going bad I may get out of control. I am really concerned about this because I feel like he trusted me enough to give me his personal number and I dont want to abuse it. It feels like a privlage to know this information.

Would it be best just to delete his number and avoid potentially bombarding him with texts on his personal phone when I am not doing well?
