Just that really. When we first met he was so kind and loving, but for the last year it feels like he is no longer on my side. We were on a day out with DC over Easter and DC commented that he was in a chatty mood, and he laughed and said he's always chatty, just not with your mum. It dawned on me that he gives his best for everyone else except me. Our conversations don't extend beyond what's for dinner and who is picking up DC. He doesn't ask about me or my day or seem to really care.
At home lately he has been grumpy and I am starting to walk on eggshells to keep his mood up around DC. I swore I would never be in a relationship like this as I grew up in an abusive home and as a result I am very aware of how people are feeling and their moods (I wish I wasn't) and I feel on edge and uneasy when I am around him. He is always kind to DC but he doesn't seem to want to be around them if I am there.
I suspect cheating (he cheated before 10 years ago - I was a fool to stay), but I have no proof and his phone is totally locked down. I have seen him using an app which I think is called 'Signal', I googled it and it says it's an app used by people who cheat as the messages disappear. I don't really know why I am posting, just feel so sad today.
