What do you think???

Nothing to do with weightloss...sorry but i want to know what people think about this situation.
Your partner ecieves a call from a friend of a friend about doing some work around her sisters house. Nothing unusual about that. This girl is very flirty and single and have had split second thoughts about your partner being attacted to her but not serious enough to bring it up. A few hours later you recieve a call from your partner saying his football team won and spoke about the game. A bit later your partner calls you and says he accidently sent the flirty girl a msg meant for you and then sent her a msg saying sorry that was meant for someone else. The msg was simply about football and could've easily passed as a msg for anyone. You don't think much of it until your partner says she was the most recently used number and that's how it was sent to her accidently???? But your number was the most recently used, then he says no it was one of the most recently used????
Many weird points: Why would your partner need to call you to tell you he sent the msg to this girl anyway? Her number was not the most recently used and you have since found out he had called someone else after calling you so her number was the 4th most recently used with yours at the top of the list and someone else 2nd. And then, being a female and knowing ways in which to get someones attention, sending a sms and then another saying the first was meant for someone else is the best way to get someones attention. Your partner is well known for flirting and has done it in front of you many times, so how do you interpret this????
