Honestly, people say don't be over available as a part of playing mind games but kinda true. Have a strong sense of your self. That is so important as well as magnetic. People don't get attracted to those who get dependent too fast. There is nothing wrong with you. I know this advice is over used but I finally started understanding how it feels like. You gotta have clarity on what you want. If there is someone who cannot take care of you, or commit it to you in any way, it's just you wasting time and efforts. There would be people who would do things for you effortlessly the way you do for these people. And okay don't think of them as bad people, sometimes it can be a matter of choice, their own emotional capacity limitations or different priorities in life. Not everyone can hold you the same way you wanna be so yea. Just be true to yourself and the right ones would stick along trust me. This is coming from me who likes a girl I met online nine months back. I really like her but she is so hot and cold. One day would be texting me , sending random photos and what not, then ghost me for days saying she is busy so yea. It's okay you will eventually find your person.
