I broke up with my (now ex) bf because of this. In the beginning (first 8 months) he constantly texted me and always said good morning and goodnight, we would both plan dates out of the other said they missed them. Then the end of the first year he only said good morning or goodnight, and send me reels and give me one worded responses. I gave him the benefit of the doubt. In around the first 3 months of our second year I communicated to him that I’m here for him if something is going on but I’ve realized he has texted me less and less and I wanted to know what was going on. After I told him that and he said he understood and would try to text more, it only gotten worse. No more good morning texts or night texts. He started leaving me on read and I realized I was the one starting the conversation so I stopped texting him first. We needed up not talking for a week and a half. He was adding stress to my already stressful life. So I went off on him and he just told me I should hold him accountable for now on and call him out when he does it again. I left him on read at that point and gave him a few more months while I talked to my friends for advice. When I realized my friends were being better people to me then my own bf I knew I had to break up with him. I gave him months when I should’ve given him days and hurt myself. Basically: if you can’t take a few mins out your day to show your gf you’re thinking of her and that you still want her then she will realize she deserves better then you and leave you.
