Love Affairs

I am a 24 year old female. Idk if something is wrong with me, or if i just have a serious letting go problem. Every time i run into someone from my past that i had a deep connection with, I want them back. Be it as a friend or a lover. I long for their presence in my life. Idk if its just the sex. Because it's not based on sex for me. I have not even had sex with my own boyfriend in 6 months. But Its like their presence brings me joy. Idk if I should just still b single because I sometimes dont feel like I have found the one. Or if I should see a psychiatrists for such confusion that I feel like I am causing myself. Opinions? Questions? Statements?
