If he is using online the league dating and hookup apps and he always swipes right, then he is definitely looking for fun. If he is still looking for other options, it means he is not 100% satisfied with your company and that he needs something more. I really cannot think of other reasons but that you are not his type or he wants more. Either of these reasons all indicates that you are just his hookup partner.
He just got out of a serious relationship. You should never hookup with someone who just end a relationship. He is not ready for another one emotionally. His heart won’t be 100% open to you. What is more, when someone says on some hookup apps that they want to establish friendship first and then maybe goes to the next level, this might be a implicit signal. Because such kind of people are usually not willing to fall in love. They are looking for something goes real slow, because they are not ready. Friendship comes naturally when someone’s intentions are pure. If they are really looking for serious relationship, they certainly do not want to prolong the process.
He uses the word “fun”. For example, I am looking for some fun. When someone says in a hookup app free that they are looking for fun, there is no doubt that they want nothing but fun, that is only hookup. Fun does not mean he wants to experience life with the restrain of a relationship. It only means they want something light, which is usually short, not long-term. Similarly, stay away from people who claims to live in the moment or I just want to go with the flow and see what happens. People who are ready for a relationship know it very clear that they want it and they are very clear with their intentions.
He usually doesn’t take you to dinner or other places unless it’s quick. For a casual relationship, the most important thing in it is sexual life. Other than that, everything is not worth it.
If he knows your period and he vanishes during that time, then he is not interested in anything other than sleeping with you. Isn’t it obvious enough? In a real relationship, even though you cannot have sex during that time, he will still want to be with you. He wants to check if you are okay, because many girls suffer from pain these days. The best time to know a guy is when you are sick. Believe me.
