Hello. I believe I can be of help to you with this issue; but I'm a little unclear about what you want to 'fix'. I think most women would feel that having other women on his phone suggests that he is having contact with other women socially. If you checked his computer, there is a high probability that he is also contacting women on adult friendship or dating sites. Here is the point: Most women would view this behavior as completely unacceptable because it represents a violation of your marital agreement about having an exclusive, monogamous relationship. That is, he is engaged in a form of infidelity and is emotionally 'cheating' on you with these other women.
Also, most women would find that when they try to discuss this issue with their husband, he will claim that his actions are harmless and in no way threaten the relationship. He will accuse his wife of being insecure and silly, in her worry about what the pictures mean. He will also accuse his wife of violating his 'privacy'. All of these claims and accusations are designed to protect his pattern of behavior---he fully intends to continue to contact other women.
Here is the real problem----you can 'take it to the bank', as they say. You and your husband probably hold different core, or fundamental beliefs about marriage and whether it is important or not to be fully monogamous. He believes it is o.k. to be married and 'mostly' monogamous, and should be allowed to cheat a bit on the side in terms of socializing with and flirting with other women, and perhaps even acting out sexually. You on the other hand, probably hold the core belief that your marriage should be a 100% exclusive and monogamous relationship.
So unfortunately, I suspect you and your husband did
not hold the same core, basic beliefs and values about marriage at the time you got married----he may have led you to believe he held the same values as you, but he in fact, probably does not.
I'll pause here and give you a chance to read my reaction to your post and give it a bit of thought, and then react to it. I'm trying to help you better understand the underlying motivations, values and beliefs you hold, versus your husband. What you do about this situation needs to be based on a very clear understanding of the fact that this is really a values conflict, and reveals a serious difference in how much you respect one another. It also suggests that your husband doesn't respect women, in the role of "wife" very highly. What do you think?
