I have never posted here before but I'm not sure who else to ask.
We have been married now for nearly 15 years and it has been a largely happy marriage with 2 young children but over the last year or so something has changed. About 18 months ago I lost my job which supported both of us as she doesn't work and ever since she has always seemed unhappy with me. I wasn't unemployed for long but my new job doesn't pay anywhere near as well and she hasn't forgiven me, saying I have ruined the family.
Since then she has been spending lots more time with her 'friends', normally this would be fine but she says these are new friends who I don't know and whenever I ask to meet them she says I wouldn't like them. Whenever she see's these friends, she either won't come home until late or sometimes not until the next morning, she says this is because they live far away from us but I don't think I believe her. It also seems like she is on her phone more than normal but when I confronter her on all this she just laughed and said I was paranoid (I have always been a paranoid person).
Does this sound bad or am I just being paranoid like she said. I still love her and I'm not sure what I would do if this was true.
