<human>: My ex boyfriend and I broke up last week from issues with fighting and being unhappy with our differences in lifestyles/communication. However, we have both voiced that we miss each other and may want to work things out.... 

The issue is, I am concerned about what has happened in the last week....specifically if he's hooked up with anyone. We plan to talk tomorrow about the break up and where we go from here, i.e. whether we want to try to work things out or if it's best to separate for good. 

I'm here to ask, if it's out of line for me to ask if he's been physical with anyone. Please, I am not looking for advice on whether or not we should get back together or not, just if it's out of line for me to ask if anything has happened. The reason I want to know is because I feel if he's claiming to have missed me and that this has been hard on him too and he hooked up with someone, it would be hard for me to believe that hooking up with someone is something that hasn't been on his mind or something he's wanted to do.

Give me a shortened version of the text
<bot>: Is it out of line to ask ex bf who may want to get back together with me if he has hooked up with anyone for the duration of our break up?
