Hi mummy~ for this situation, it’s really up to you to convince yourself. If you cannot trust, then pretend to call up the number and see what the other party says. If you can trust your husband, then don’t bring it up anymore. He might be really speaking the truth but we and our sensitivity occasionally worsen the situation. (Almost drove my husband crazy on occasions 🙈)
Hi Mum, This looks like an innocent mistake as the call lasted only for 23 secs. But if you are still not comfortable, I would suggest speak openly to your husband on how this makes you feel
Try calling the number yourself. He was probably curious, hence the “innocent” 23sec phone call.
