I don’t know how to feel..

Hey everyone,

This is my first time posting. Let me tell you about the situation. I have a male friend. We have been friends for a total of 10 years. Him and I use to talk just about everyday and such. He was more like a brother to me. Well 3 years ago he met a female. And him and the female got into a relationship. He told me he doesn’t think it’s best for us to talk anymore. Because she had an issue with it. So I told him okay and that I’ll miss talking to him because he’s my best friend. But I understand where she’s coming from and I didn’t want to argue about it so I just accepted it. So a couple months ago I randomly got a Facebook message from him apologizing about how he shouldn’t have dropped me as a friend and etc. I accepted his apology. He told me he got married a year ago. I told him congratulations. He kept the convo going. I was telling him I didn’t want to be disrespectful talking to him and the fact his gf/who is his wife now didn’t want us to be talking back then I’m sure wouldn’t be okay with it now. He started ranting about how his marriage was troubled and what she does etc.. I couldn’t really have an input because I don’t want to speak on something that I didn’t want to be involved in. So as months passed we talked up until this week. He would still rant about their issues. And how she was treating him and he felt as if he was losing his mind. Again I couldn’t say much but whatever makes you happy go with your best decision. He said he didn’t trust her and it seems as if when she comes home their dog growls when she comes in like he senses bad intentions. So he texted me two days ago and I hadn’t heard from him since. Im a type of person to worry. So I was texting him and I notice he hadn’t responded. I begin to worry more. I finally texted him again not too long ago saying look I just need to make sure you’re okay just tell me that. He finally texted back saying he’s okay. I said well that’s good. I left it as that. I saw my message wasnt delivered. I’m thinking okay maybe he doesn’t have signal. I get on fb messenger to look for his name and it looked as if he deleted fb... he didn’t. He blocked me. Blocked me from fb messenger and blocked me on his iPhone. I don’t know what I did, I don’t think I did anything but worry. And I’m sure again he will eventually unblock and send some sort of apology again and being who I am I’ll accept it. This time if it happens I’m thinking of saying forget it. Advice? Did I do something wrong here? I don’t want to be disrespectful and text someone who’s married but we are strictly friends only etc......
