Does he miss her?

Men and Women are different in many ways. People often have different attachment styles and ways of expressing affection. And it sounds like Tina and Adam have various ways of expressing and experiencing affection.

there are different ways we show someone that we care about them. some people just tolerate distance better than the others, i guess. but however, i believe that women are usually the ones that miss their partners more, if they really like them

As long as he communicate and responds I guess its okay. But if he don't do efforts like starting the conversation, I mean its ok if he don't do that everyday but the fact that he starts the conversation every other day its okay, I think... But if it is Tina who always reach out and the guy dont reply back everyday... Or everytime tina text her I think there is something wrong. I mean guys don't usually clingy but if he really love that person he would also make an effort to make her girlfriend assurance that he really care and love her... Doesnt matter if he don't do video calls... But call and messaging her from time to time is enough.

Every relationship is different. The fact they communicate is evidence he misses her.

Men have different ways of expressing their feelings. I can't answer the question without knowing more about their relationship. Have a good day.

i think she is betetr without him. love or relationship should be equal.

They are communicating so it's hard to say.
