So we have been together now 13 years. First few years of relationship i worked away from home. One trip coming home she said she didnt love me anymore. It was so put the blue. I admit i shouldnt have but ended up checking her phone and while i was away she had been txting my best friend every day. It was mainly just general chit chat and only one thing sexual where he asked her what her fav position was. She until this day if ever comes up maintains he was jst a friend to her. I was like im Supposed to be your best friend and when i look at my txts while i was away there was maybe one two txts a day compared to all day conversations with my mate. Anyway i left for few weeks and she begged me home which i did. Years later after second kid together she began going out most weekends not coming in til early hours of morning. When i told her of my concerns i wasnt on her priority list She proclaimed that because she never had many friends and we were young when first together and i worked away that she missed out on alot and was genuinely just enjoying having fun with friends. I can understand this. But added to this when looking back tht i never noticed at the time. 90% of nights out she would say her phone was going to run out of charge. Always took hours to ever reply to my txts that only ever said how are u babe hope you having good night. One time i came home and noticed a txt from her which she sent an hour previous to me reading it which said… call me asap when u get home..i said is everything ok? To which she replied (an hour later remember) aw ok i just thought i left the bath running im just leaving my sisters house. I dnt no why i was stupid at the time to not even realise how daft tht sounded and adding to tht fact her sisters is only a ten min walk away. Anyway more things similar to this. No clear cut evidence jst a feeling
