I think I just need handholding really.
I’ve been with my partner for 8 months- known each other for 2 years.
Never lived together- both have kids from previous marriages.
Always been a happy and healthy relationship until maybe 2 weeks ago he started acting really weird- not replying to messages, when I saw him he would over explain himself about where he had been etc ( for no reason).
We had a discussion and I explained that he ‘didn’t need to explain himself to me as I trust him and have no reason to question what he says to me’.
Until that point that statement was true but then one day last week he was messaging me about some stuff he was looking up on the internet. He works in a small building that I occasionally work in too as we work in the same industry and I happened to also have a meeting there that day. I noticed that his car wasn’t there, and as he was clearly on the internet and not working I messaged him saying ‘oh have u managed to get a day off you lucky thing’.
He replied ‘no I’m at work’ and a bit later ‘being naughty and using the work computer for personal use’.
I suddenly got this weird sinking feeling.
I have never had any reason to suspect him before but after he had been acting so strange I had this weird hunch.
When my meeting had finished I went to the car park and Jumped in my car- he was still messaging me as though he was at work but I knew if his car wasn’t there then he was unlikely to be there. He never doesn’t drive and is a creature of habit and always parks in his allocated space.
I m not proud of this but I had a feeling he was with his ex so I drove past her house-
His car was there.
I know the kids weren’t there as he had dropped them to school that morning.
I now don’t know what to do.
Do I ask him outright?
Am I acting like a deranged mental person?
I do have BPD though I have therapy and work really hard to not let it impact only relationship decisions.
