I've been with my husband for 23 years and we have two children together. Just recently I feel that I no longer know him. We've always been so close but his recent behaviour is out of character. I happened to be using his phone ( he uses mine too) to surf the web and found that he'd been looking at pictures of women on Instagram. I know this is probably not a massive deal to some but to me it's a massive issue. I don't have self esteem issues but it's left me wondering why he would do that especially as he's always been so sweet, loving and attentive. The other issue is something related to his business where he's gone ahead with something that we'd discussed and I'd expressed that I wasn't happy and he said he wouldn't go ahead. Again I happened to be using his phone to look at recent pictures of our kids that we'd taken and came across the fact he'd gone ahead. I feel as though I don't know him. He's not the man I thought he was and just seems to persuing his own agenda. We've always had a good relationship but it's left me wondering what else he is up to. I've spoken with him but he says he doesn't know why he did either of these and that he loves us but feels empty inside.
