About a month ago I went off on my boyfriend because I was frustrated with things between he and I (his constant working – 7 days a week), and I was also too involved in a relative’s drama and took it out on him. He didn't speak to me for about4-5 days after several apologies from me. Well, last Thursday I called him because we hadn’t spoken via phone, only very short texts for almost 2 days. He was being very strange on the phone (he was at work but usually has a quick convo). Instead of going off because I remember the last time, I told him I was getting upset and I was getting off the phone. I haven’t heard from him since. We had plans this weekend, which didn't happen even after I sent a text Friday asking if we were keeping our plans. He never responded. We’ve been together 4 months and things were good prior to this. His schedule is changing where we’ll have more time. We just had a deep talk about 3 weeks ago confirming that we are happy together and want to remain together as long as possible. Even in our discussion I explained to him that going silent and shutting me out wasn't the answer. He said that's how he handles his emotions. And now this disappearing act, again. I haven't called or texted since Friday because I did nothing wrong. I feel I have a right to ask questions and express my disappointment or hurt feelings. I'm not going to walk on eggshells for fear he'll be invisible again. Should I walk away now and count my blessings?
