Method One of Three: Making the Transition. Focus more attention on your partner. In your fast paced world of cell phones, social media, and busy schedules, you may be distracted a lot. When you start a relationship, try to focus more of your attention on your partner. This means you should put your cell phone down and stop texting while you are with your partner. This will let your partner know that you are in the moment and want to be as present as possible. This will help make your relationship stronger and last longer.
Dating someone exclusively is having a monogamous, committed relationship in which you and your dating partner agree to only see each other. Getting to the exclusive stage should normally take several months to let you and your dating partner spend enough time together to know that this person is someone worth the time and effort. Working together in an exclusive relationship gives you the skills you will need later to be in a loving, caring life partnership.
Only after you both agree to be exclusive, in no uncertain terms , can extracurricular-shenanigans with other lovers be considered cheating. If he never said he was going to hookup with only you, then he has no duty to keep his pickle off of other plates. Of course, this goes both ways.
