I met my husband online strictly as friends and progressivly it turned into something more. After almost a year of just talking we met, a year after that we married. We have now been married a year and I have just discovered that he has been talking to other females (not sexual just flirty) and is signed up for dating sites. I confronted him and he said he was just “curious” and was just “messing around.” I know I have been depressed and not the same as I recently had to quit my job due to illiness and am in pain constantly, though hes been extremely supportive in that aspect. But Imo, he shouldn’t need to be seeking out the companionship of other females let alone flirting with them and leading them to believe he is single even after hes asked if hes married he says hes “single” and sometimes he tells them hes “dating someone”. I confronted him about what I found and the messages I saw, and he apologized and said he didn’t mean to hurt me. Hes a really good husband and I love him very much, and he says he loves me as well. I feel like the intent is/was there and its hurtful. We have never had any issues before this. Help I’m so confused, is this cheating?
