May I have a women perspective on this?

I just got dumped by my 1st girlfriend. She broke up with me because I wouldn’t be honest with people at work about our relationship. I was trying to avoid the messiness of the work place but I ended up only considering my feelings and not considering hers , that was my mistake. When someone would ask about our relationship I would say “ no we’re just friends”, or “ no we broke up etc”. Eventually she sat me down told since I’m telling people at work those things then we should just be friends. Ever since the break up it’s been really hard. I was being too pushy in the first week or two by trying to fix things but I only ended up pushing her away. When I would try to talk to her about she would say “ I don’t wanna talk about it right now”, which I understand, but I wasn’t thinking clearly so I panicked and became too pushy. We however have a few convos about the situation. She seemed really upset and explained my actions made her look like and idiot and that she got caught in the middle and it made her look like a liar. She said it was too much stress combined with both of her grandfather in the hospital, so she had to let something go (unfortunately that was our relationship) Then by the 3rd or 4th week I asked her and she told me that she is seeing someone else. (She was wearing his jacket at work, I didn’t recognize it so I just asked her straight up.) It’s been hell for me emotionally. She said she lived and cared for when we were together. How could she move on so fast. A week ago I accidentally liked one of old reposts because I got notification at work that she reposted something ( it was about her current relationship) Igor reason I got caught up looking through her reposts and accidentally like one then unliked it (my fault) I figured maybe she didn’t notice. later that day we had a friendly convo at work so I thought we were in a good spot at least, but then I saw her reposting mean spirited stuff ex boyfriend stuff on tik tok.
