Hi - I have a long term relationship with my fiance, she is 25, I am 34, I also pay for everything. We have three children together, the past few months she has got very toxic, unfriendly, arguments telling me to leave, and regularly making friends with a former single mother from high school.

​

They have recently been hanging out together on friday, saturday nights almost every week. She left her google account open, and it showed they stopped at an apartment building for 15 minutes, when I brought this up to her she freaked out, told me I was spying on her and got angry. The past two times she has went out, she takes a bath as soon as she gets home, keeps her phone inches from her face.

Also her Facebook password has been changed, and the messenger app on her computer now has been deleted. She tells me I am being crazy, insecure, when I bring this up, but every fight she tells me to leave. She recently took a pregnancy test, when she saw the results balled up on the couch and cried, seemed very odd to me. I messaged a guy on Facebook I had minor suspicions about and he was very flippant, and avasive, he messaged her account asking "why is he asking questions", Your thoughts?
