Im a guy mid 30's, with partner 2 years and basically helped bring her daughter up. Last couple of months have not been ideal but nothing major has gone on. Partner started her new job 6 weeks ago and has also been working at home on a night which is okay and texting other staff about work, which is okay. The past 2 weeks she has been texting a certain work 'friend' a lot. I mean a lot, first thing on a morning all morning until work and then on a night all night to bed, to a point where I feel he is a priority over me and gets all her attention. I confronted her and she went off on one saying I'm paranoid and jealous and have anxiety etc etc he's a good friend and I'd never risk losing my job. Now, i know he's single and tbh he's not her type at all, not physically at all and he would definitely be punching. Wherever she goes she has phone in hand, never without it and checking it every 30 secs to a minute and being very shady around me with it. Ive seen the way she smiles at it too. All of this is not normal behaviour for her. Its very very strange. Shes doing exactly what we were doing when we first started dating and fell for eachother. She says she loves me and doesnt want to lose the only father figure her daughters ever had but I feel like she knows what shes doing and is now rubbing my nose in it in the hope i will say something so we can row and she can push me out ? Am I being unreasonable ? Is it all in my head ? Would you agree this isnt normal behaviour ? Has she had her head turned ?
