<human>: I've been single for a whopping 4 months now and this is the longest I've ever been single since I was 16 (I've only had 2 boyfriends and 1 quasi boyfriend). My last ex dumped me and got with the girl he was texting during the last month of our relationship and kept telling me she was "just a friend" like 2 weeks after our break up. I've basically been convincing myself that being single right now isn't a bad idea and I know that I have somethings about myself I need to work on. For example, I always worry that I'm bothering someone else or they don't want to be with me and I need to work on my self confidence that I am a good and fun person to be around. That I am worthy and someone would be lucky to have me. I'm planning on just being single, traveling, making friends, and doing things that I enjoy. I can't tell if I'm just being bitter that my ex (who was telling me how much he loved me and that I was wonderful to him during our break up basically moved on to a new girl 3 weeks after our break up). Like what does it even really mean to "work on yourself" What does it even mean to "find yourself". If I meet the right guy during my time single, I wouldn't object to it but I won't be actively seeking out someone to occupy my time and mind.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Confused if I'm just being bitter that my ex moved on so fast or that being single is a good idea. Not really sure what it means to "work on yourself" and "find yourself".
