Why is falling in love so hard for me? ?

I’ve always never had it easy when it comes to love. It seems like everyone around me has children, marriage or boyfriends. But when I finally get a chance to date someone I actually like, people watch me like a hawk.. and end up ruining for me. I’ve even come to conclusion of not talking to the man I like on social media. Because other women jump in or men block him from getting to know me. It’s so hard for me and I never know why it’s like that for me.
