Search Results: saying goodbye

Let's say you're going off to work or something of that sort, how do you say goodbye to your significant other?
If you do kiss them, do you kiss them on the mouth, the cheek, or the top of their head?

Im in love with this guy. We have a deep connection. 4 month into dating him, He told me that he actually already have a fiancee. I was shocked and devastated. He says he doesn’t really in love with her. The relationship with her is just obligation and family pressure. He says he has genuine feelings for me and love me. I felt confused and shocked. Somehow we still in touch because he still wants to see me and i still do too (my mistake). We kept seeing each other.
One day, i found out that he is about to get married in few days through social media. Last time i saw him was 1 week before the wedding day and he didn’t say anything. We kept talking until the night before the wedding day, he still texted me. Its been 2 days after the wedding day and I didn’t hear from him anymore. I know that things between us should end, but i feel so Unfair if he ghosted me after everything we’ve been through. I just wish i get a proper goodbye.

My question is should I give it some time and then call him for explanation or just ignore him and just let go without saying goodbye?
