姐妹門幫我分析一下

認識一男已有5個月, 平時幾乎天天上班時間通email,we see each other every 2 weeks, we had physical contact, but I saw he is still online ( match.com) almost everyday, I cancelled my membership, but still want to know what he is doing.Is that mean he is not that serious or just play with me? what should I do now?
