Am I overthinking?

[Soont]

I've found myself with time on my hands since being furloughed and have had time to think about stuff and I need opinions about if I am over-thinking this stuff or not. Basically, the following things have happened to me spanning a period of 9 years and written down it looks like DH has been unfaithful.
Lipstick found in DH's car).
Strange strap found in DH's suitcase after a trip.
Item of my clothing went missing and then resurfaced later in a place I had emptied looking for it.
Duvet smelled of perfume one evening after I'd been at work.
A handful of odd social interactions when bumping into people he knows and I didn't (i.e. he didn't introduce me at all to these people, one woman looked at me almost in surprise and looked me up and down while he was talking to her (like she was curious rather than being horrible, another time a guy basically totally blanked me the entire time DH and him were talking like I was invisible).
A seeming reluctance from DH to go out locally but still went on holidays.
A previous Android phone DH had I've subsequently realised was dual SIM, but he's never mentioned he had dual SIM.
A categorical denial about using messenger, says he doesn't know how it works, but subsequently found secret messenger activated and a secure pre-key established (for secret messenger conversation) on a very significant date.
What would you think? (The lipstick, perfume etc I know could suggest DH might be using on himself but he's definitely not that type).

Did you post about the strap some time ago?
Have you checked phone bill? Bank statements?
Is he still wanting sex with you?.

Hi OP you’re probably not overthinking but it’s definitely best to have a chat with him, see his reaction and hear what he has to say for himself. The messenger thing and the lipstick is kind of fishy to me.
Do you think he’d bring another woman into your home? If it isn’t his perfume, it yours or one you recognize then I’d surely have a word. What does your gut tell you?

I've posted about the strap before but bizarrely I noticed two other threads about a strap last year Nothing on phone bill or bank statements but can only go back one year. Yes he still wants sex with me.

Does he go out local without you quite often? Go out to the shops much longer than expected or late home from work?
All the things you mentioned seem dodgy tbh.

Already had the chat and he categorically denies.

I would never in a million years think he would bring another woman into our home without me knowing. The perfume wasn't mine. At the time I was working so hard it was when I flopped down on the bed after coming in from work so I mentioned at the time that it smelled of perfume and he said it was probably fabric conditioner and I just accepted it. Thinking about it now, I do all the washing and it didn't smell of any fabric conditioner I used and I don't know why or how I let it go (other than I was working full on and was very tired and probably forgot about it). I'm now just like

Prostittues? Just because of the phone thing and lipstick in car

Was it the strap that people were suggesting was off a top or bikini?

Some of the things sound dodgy some don't. I thought each device had a key for secret messaging?

No, you are not overthinking. Your OP is full of red flags.
