H left me in June after big argument. Minimal contact him only texting about dc. Ignores me in street drives past me refuses to speak to me. His dad died just over a yr ago and he changed into a different man. He's told me he needs more time and he's not right in the head. I'm holding onto the fact that he might realise what he's lost and talk to me and try to fix our marriage. My heart and head are telling me 2 different things. Am I wasting my time?
