No not always. Guys need lots of breathing room and space. Ask yourself if you are needing too much time from him. Remember he will not have a chance to miss you if he's with you all the time. Give him time apart and that will create a desire to see you again.

Hi Phillyevol,

It's human to jump to the worst case scenario, but it doesn't mean it's true. In all relationships there comes a time to evaluate what you are getting and what you need. If your partner feels there is something missing, it's extremely important for you to have an open, honest conversation about what you are each looking for. That being said, if he is interested in sleeping with others, it's his right to go off and explore that...and it's equally your right to set out and find someone that is only interested in monogamy (as you deserve).

Best of luck to you!
