My husband went out on his work Christmas do which he tells me finished at 1am, but he didn’t return home until 4.40am. He tells me he was sharing a taxi with a co-worker as they were both going in the same direction, he was supposed to drop off first but says she was very drunk and didn’t want to leave her alone with the taxi driver after he got out so he took her home. He swears nothing happened said they went in had a cup of tea and chatted, and that her 21 year son was upstairs - my brain is telling me this doesn’t happen! He returned home being overly chatty and nice. His location had also been paused on his phone at 1.20am, said he didn’t know, well that can’t happen by itself can it? I am so upset it’s tearing me apart - I can’t live with someone that has been unfaithful to me. Any advice pls.
