I recognise parts of your torment. I was in a 16 year relationship where for the last 6 years there was no physical contact or love or support or even cuddles or hand holding. I loved him dearly so I tried to speak to him about it, I tried to instigate contact, I tried everything. We lived like brother and sister for the last few years, he’d sleep downstairs, we were like ships passing in the night, we sat in different rooms watching our TVs. My heart broke as I pined for that contact. I eventually found him looking at porn and going on dating sites, porn I could deal with, dating sites no way. It killed me at first splitting up and he denied it and gave me the sob story about how much he loved me, I gave in and we tried again, only for it to last around 10/12 weeks before it crept back to exactly how it was before. He’s been gone 4 years now and I have never felt better, I’m calm settled, yes I miss him at times, but I sit and make myself replay certain days that stick in my head about the way he treated me then I emerge with a smile and a content heart. So I’d say take each day at a time you will miss your life with him as that’s all you know at the moment but trust me take small steps and things will get better. Come on here and chat if you need to, there are lots of us willing to support you.
