Relationship advice needed
I'm new to this site. I don't know where to start. My problem is I never date anyone before even though I'm in my late 20's. I hang out with so many people, get to know them but never last more than 3 months. Sometime I close my eyes and go for the relationship that I hope it'd work out. However, it never been like I expect. I wonder why relationship so hard. I just give up at one point, and be confident, and love myself as long as I'm happy with my life. I do feel lonely sometime, specially holiday or family/ friend gathering party. People keep asking me when they want to see my guy. Those moments make me wonder when someone will enter my life. I do take things every slow, and take time to like someone, but when I find good guy, I will chase that person until the end. I don't know why I talk a lot here. I just want to let it out since they are in my thought for a long time. I apologize for a long paragraph.
So at my new work, I have crush on my coworker who moved to work in another state last year. I sometime IM him to ask about his life. I never hang out with him in person since I only know him 2 months during the time he was working with me.
Recently, I have his number, and we chat more often in WhatsApp. P/S: he told me to download this app since he use it for people he cares about. We share the same interests and he told me we should do this/that sometime together. He is working in another state right now. Because of the Covid-19, we can't travel/ or come here anytime soon. I don't know if he is interested in me or not. Or just be polite/nice. It's just hard and weird to ask straight forward.
On one hand, I don't want to keep texting him a lot, it seems so desperate, but the other hand I feel like I should text him more to get to know each other, and to know more whether he is really interested in me or not.
He also has the same manager as me, so I don't want to make him feel uncomfortable or it will put me in hard position if things don't work out.
What should I do? I think people have different points of view, so it's better to ask. I appreciate if anyone can give me advise.
