My boyfriend and me just moved in a month ago. I went back home for two nights and three days. In that short amount of time by neighbor friend swears she'd seen him talking and being flirty with another girl, if that wasn't enough I guess he followed her to some place. I don't know if this is true but it definitely has me uneasy. I asked him if we had any visitor while I was gone and he said no. I honestly don't know what to think or how to go about it
