I've been with my partner 8 years and we have 2 kids. Around a year ago I noticed he had "liked" a picture on Facebook of a girl who we used to work with posing. I was annoyed at this and told him I found it disrespectful. He said he didn't mean it in that way and wouldn't do it again. A couple of months later I found out he was liking her pictures on Instagram (which I don't use) I straight away thought this was so I wouldn't be able to see and we had another row and he again convinced me it wasn't in that away. A few more months later I went on Instagram and found he had "liked" all of her pictures and she had sent him a 😍 emoji. I don't think anything has actually happened but told him I was really upset and about it and for him to then continue to do it after her sending that again I found it disrespectful. He again promised it wasn't anything and said he would block her off it. Its been 6 months since the last incident and I have just found that he has liked another picture of her but on his work Instagram account. I really don't know what to make if it all. I'm not normally an insecure or jealous person and I understand men like other women but this isn't some model this is a person in real life who we both used to work with. And any other normal person wouldn't keep going back to her. He's spent a few nights at his mums and she's tried to reassure me that he's said he loves me and he isn't doing it in that way but then why can't he stop? He stayed at home last night as I've been ill but think I'm going to ask him to go back his mums tonight. I really love him and I don't even look at anyone like that let alone make them aware by liking their pictures. Has anyone else been through something similar or have any advice?
