Help feeling depressed!!!!!!!😭😭😭😭😭😭

Sooo I haven’t been with my ex for about 5 months now .. and at 4 months I found out he was having a baby with someone else already . Mind you I was with him for 6 years.

The past couple weeks I have been fine and moving on and actually happy .

But just recently I’ve started to think about him a lot .. is this normal?

I hate it . I keep myself busy and haven’t thought of him but just recently I’ve been having dreams about him and just thinking about him ..

Plz tell me if this is normal . Idk what to do . It hurts so much that he hasn’t even tried to see how I’m doing .. I just don’t get it . I don’t want to be with him but he was my friend for 6 years . Does he not feel the same? We still knew eachother for soooo long ... plz help feeling really depressed .

I just don’t understand how he Cn move on so quickly . I know we weren’t right for eachother at all but at the end of the day I loved him . I just wonder does he ever think about me? I just dnt get it . Why are guys so stubborn . Why can’t he reach out ughhh
