When I couldn't pay to keep my phone turned on, I didn't warn my ex boyfriend that it was getting shut off. He called constantly when I kept telling him I didn't want to talk. Talking mentally exhausts me and I start getting progressively bitchier. I didn't know it'd be off as long as it was. After 3 months, I had to get a new number because the phone company deactivated that phone number entirely. I didn't give the new number to my ex because frankly I didn't want him to have a way to contact me. The constant calls and texts felt like harassment. I was tired of it. So I'm not giving him this number. If he calls the old number, all he'll hear is "this phone number is either out of service or changed". That's what he's been hearing for the last 5 months. I feel bad that he probably thinks I just voluntarily changed it without a warning. I didn't voluntarily have it off. I didn't have a job and a phone was the least necessary expense. If I see him in person, I'll explain. I'm still not giving him the number. I tried being friends with him and I was still miserable. But he does deserve an explanation.
