How to be okay with being alone ?

Hello ladies . I need advice .I just stopped dating someone. He was not officially my boyfriend and we were not dating for that long so I’m not too hurt about him , but I guess I’m just thinking of what could have been. He also did the bare minimum, if I told you guys some of the arguments we were having so early you would tell me that you were glad I left him. We had so many dates and trips and everything planned out , I was really excited that I finally had someone to experience those corny couples things with.

After doing some thinking , I realized that I Have major attachment / abandonment issues and I hate being alone . I am not happy with myself so I look for love in other people . How do you guys deal with being alone , or being single and happy?
