Should I be worried? Please help

[IsabellaMoltisantixx]

For the past few days dp just seems s bit more distant and snappy,
For example, he would always text me in the morning when he got to work (he gets to work super early) then throughout the day and especially at lunch
For three days he hasn't done this,
He also was a bit snappy yesterday
Should I be worried?

How long have you been together?
His is basically 'checking out' of the relationship.
Any signs of OW?
Is he on his phone more?
Home a bit later than usual?
Working out?
More aftershave?

This needs a lot more background...

From this, he could just be in a bad mood or upset with something you might have said or done.

Don't jump to an affair fgs

Have you tried talking to him? Asking if he's okay? Asking if he's upset with you?

Well there's obviously something amiss, but if no obvious cause is jumping out at you then you need to ask him. I wouldn't jump to conclusions - it could be any number of things. Problems at work, money worries, family worries.....

But you do need to ask him what is wrong and don't be fobbed off with "nothing" because such a sudden behavioural change has something behind it.

Ask him if there's a problem, and can you help?

Thanks for everyone's fantastic fast responses
Been together 15 years on n off. Had a few issues with him, we have two children. Trying to make it work for younger dd who's only 9 months
But hard when suddenly mood changes
I just hate it as before he seems really loving and happy n then out of nowhere snapping, putting me down etc.
He has a job where he works away n works in teams with many women or loads of training. I guess I'm just paranoid. He's previously cheated long ago just after first dd was born :(she's 10 now) I get worried n guess I'm just after any signs etc
