DP past haunting me

[PollyPickle]

First time poster. I'm currently heavily pregnant so I imagine my hormones are playing havoc.....however been with my DP about 5 years and really happy but today I found some old flirty messages on his phone from before he met me. Not a problem everyone has a history etc BUT they happen to be to a women I work with and had no clue they were ever romantically linked. I know it shouldn't matter but it makes me feel really awkward especially as I don't like this woman for many reasons. I don't know why but it's really eating me up, I'm not being rational and my DP knows somethings up.
Does anyone have words of wisdom to get me to snap out of this. It dosent help I feel like a bloated hormonal whale due to pregnancy. Thank you

Can I just gently ask why you were looking at old messages on his phone? Do you have any reason to doubt his trustworthiness?

I think it was a mixture of boredom I was also using it was mine packed in and I thought I had logged in as me. That's why I recognised this person. I realise I have been stupid and totally irrational

I would wonder why he saved them >unhelpful

Unless the messages have been automatically backed up and then download to a new phone I'd also be wondering why be had saved them.

Sometimes people just don't delete stuff. I don't see anything untoward about that.

It's his past...just try and leave it there and carry on with things.

As you weren't snooping...you could let him know what you found.

I don't delete old messages on phones I'm not using anymore, as I don't have anything to hide.

Just speak to him, and say you've seen them and didn't realise they were involved. Make it clear that it's your insecurity, not that you're accusing him of anything terrible (as you say, they are all from before you got together) He should be happy to talk to you about it and reassure you.

Thanks everyone. I don't think the old messages are a worry in terms of him saving them. I agree it's my insecurity and I will explain it as that. However I think it's highlighted that I need to work on my insecurities and am planning to do something nice for myself this week, like get my hair cut just so I can feel a little less crappy.

Old messages wouldn't bother me. I don't delete old messages so they're probably a few exes on their from moons ago, I don't care to look.
He's with you, not her.
I'd be more concerned with why you were looking at 5yr old messages tbh
