How do I get in contact with him?

I saw my ex last Thursday. I guess you could say I stalked him because I knew where he was going to be on such a date and at such a time. I only did that because we hadn’t talked in two months. We talked for two weeks after I kicked him out for no reason. Yes, no reason because he honestly didn’t do anything wrong. I thought we were working through things, but then a bunch of things happened and everything fell apart. He lost his phone and a lot of things happened in his life – not to mention that I had also kicked him out. I tried emailing him, but never heard anything back.

Anyhow, when I saw him, he seemed really happy to see me – shocked, but happy. He kept saying, “this is crazy.” Anyhow, we talked for a bit. It was a little awkward, but we hadn’t talked in two months. He thanked me for a phone card I had left at the apartment (he still has keys and still has the majority of what little he has there.) He told me he had gotten a phone from his sister, but he didn’t have a sim card; therefore, the phone wasn’t operational. Before I left, he told me that I could email him. I told him that I had tried and he had this confused look. He asked if I had sent it to his gmail account and I said I didn’t know he had a gmail account and that I only had his yahoo address. He said the gmail was the same as his yahoo. He also asked if my phone number was still the same and I said yes. He initiated two hugs – real ones, not the faked, forced ones. I told him I was going to leave something for him at the apartment.

It’s been a week since I saw him. I’ve sent two emails – one to say it was nice to see him and that I looked forward to hanging with him in the future, the other to say that I had left a little “care package” at the apartment. I bought him a sim card so he can hopefully get a phone up and working. I haven’t heard anything back from him. He comes to the apartment to change out clothes less and less. It was two weeks, then three weeks, and now it’s been a month since he was last there. In the past, we used to only be able to communicate through emails and sometimes it would take weeks for him to respond. I’m just so anxious. I feel like I don’t have many options at all. I’m just terrified that I’ll never be able to contact him again. It kills me because he seems to have gotten in touch with everyone else in his life, even without a phone of his own.

Honestly, I would think that I need to try “NC” again because I still think about him too much and let this whole thing stress me out; sometimes, I cry every day. I think “NC” is a great concept; however, I’m wondering how good it is if I already have no contact. How can I contact him after “NC” if I don’t have a number for him and don’t know where he’s staying? Please help!!!
