We have came on holiday with the kids and my partner keeps looking at another women who is here on her own with two young children. She looks quite young and slim and all that. But everytime we walk past he looks at her, like stares at her and I think he knows Iv seen him. He doesn’t seam to look at other girls walking around in bikinis and stuff just this one girl. We have been together almost 3 years now and have an 11 month old child. We are also engaged. Should I b worried it has upset me very much
