Will he think I am crazy?

Ah OK got it - it's a bit different from what I thought then. Sorry for giving unhelpful advice! I reckon just hover in the background being supportive if he needs you and put all thinking about the relationship on hold for a week or two. Don't worry about the pocket dial, style it out, it won't matter.

People make accidental calls or pocket dials all the time, and it shouldn't be a big deal. You could just send a text message saying "Hello <name>, sorry, accidentally called, hope you are going well."

Perhaps I should have said, that it doesn't come across as believable, therefore, if I were him I would be inclined not to believe you.
In saying that, he has much bigger problems this week to really give much thought to if you're calling him off a different number or not. Even if you did (which you didn't), it doesn't really matter.

If you really care about this man, just be there for him and what he needs. Don't try to take the lead on contact/ assume what he needs/ tell him what you think is best. He is grieving. And he has said he doesn't want space. So just check in with him and be kind and ask how it is. Maybe don't expect the phone calls, and even if he says he is going to call, and doesn't, give him a break for a couple of weeks over it.
Afterall, it's not surprising if he said he is going to call but doesn't/ slips his mind days after his mum has passed away.

I think, if you really like him and see it long term, then you just need to be there for what he needs for the next couple of weeks at least. Then once he is home if it is a pattern, perhaps reassess what you want.

He has said he doesn't want space? You've decided he wants it? Right after his mum has just died...
Sounds like you're creating drama to get his attention.
I think that's more problematic than your son calling him off a work phone (something I don't believe when you say - sorry - but I don't think he will either).

I think you need to stop making this time about you, and start making it about him.

I get it, you're at an early stage, he's got something important going on and you don't want to look like you're trying to intrude. You feel extra unsure of protocol because your attempts to offer space/support didn't go well. Don't worry though, a missed call is fine, if he calls back just explain briefly like you would with anyone. If you don't weather this it wasn't because of the call, it's because you're not a good fit, compound by a major bereavement happening at an early stage.

Blimey, if there's this much drama at the start of a relationship, it doesn't bode well does it OP? It's supposed to be fun at the beginning, not complicated and messy! 🤦‍♀️

I get it. People pretending not to are just being rude, not everyone has perfect written English.

You were seeing someone, probably quite casually, and he said his mother died and he was going abroad so needed space and you agreed to leave him alone for a bit.

But you are thinking about him and hope he does come back and pick things up again.

Your son dialled him by mistake and you are worried that you look like you're trying to find excuses to call him and seem desperate.

I think the reality is OP that you know he is not as into you as you are into him. That's why it bothers you. Take the power back and just ignore him, don't call again or try and explain. Assume he isn't coming back and get on with your life. Then if he does, HE will need to chase YOU.

You're oceryhinking this.bif he asks, tell him what happened. If he doesn't, no harm done.

You're overthinking this. if he asks, tell him what happened. If he doesn't, no harm done.

I would say nothing unless he asks. Then just say casually that it must have been your son by accident when he was playing on your phone. Don't make a big deal of it 🤷‍♀️

Eh? How can you say, "my date with whom we don't speak" when you just mean you (singular) don't speak to him? You mean, "my date to whom I don't speak," presumably.

Anyway, I wouldn't worry about it. I'd just leave him wondering.

If this is a partner you’re in regular contact with (as in yesterday) why are you so concerned he will think you’re desperate?

If you’re in a relationship and he realises you called from your work number won’t he just assume you tried to ring him from your work phone? Why would that be an issue? Has he asked for space or broken up with you? I’m so confused why getting a missed call even if he knew it was your work phone would concern him unless you’ve been hounding him from your usual number first and been asked to stop?

Theres way more to this I think!

My date?

Why are you calling him 'my date'? is he a bf? how many dates?

If he doesn't know the number he'll assume it was a wrong number and mofe on with his life!

I agree with @5128gap .

How can your son watching you tube videos get your work phone. Open it, find his number which you’ve not recently called him from that phone so wouldn’t be at the top of the list, and call him from it?

Do nothing. One call doesn't look 'desperate'. A message or call to say that your son called him by mistake sounds a bit 'yeah right' so might seem like looking for excuses for contact. If you don't contact him again he'll soon realise you weren't desperate.
