HI all i am new here. I have been with my partner for 10 years, i have 3 kids that he took on (sadly their real dad died). over xmas i found messages from another girl on his phone, he's been offering her money and food, I dont know her or her name, and pretty sure she's not from work, she has a partner and knows about me, several times she's asked me to go over with him and he's made several excuses like i'm isolating, i'm working etc. I questioned this messages last night, at first he full force denied it then came clean about 1 hour later saying she's from school and has mental problems and is always asking for money. I found more messages that hes sent to her asking if shes missing him, which she replied Maybe. Then we had a full blown argument that I don't trust him and he's done. I fell asleep shortly after, we don't live together he has his own place.
Also he went and bought him something yesterday for £600, when we are supposed to be saving for our delayed wedding and moving into together and he was like yeah so means i can spend more time at home.
would this be ringing alarm bells? We had a lovely xmas day and this has totally spoilt it
