How do you deal with boys who cannot express their feelings?

I (23/F) have been single since 2016. I won’t even call the two “relationships” that I had before that as relationships. Both of them lasted for 6 months put together. I was quite immature then. Shortly after the second one ended, I went on Tinder and I was introduced to casual sex. Fast forward to 2020, I have taken a vow of celibacy, because I met quite a lot of clowns (and fucked them) and now I’m desperate for love. I speak to a guy and he says that he likes me, but he won’t express what he is really feeling. He’s just ambiguous when I ask him about it. He just says that if an opportunity arises, he would like to date me and that he cannot really express how he feels about me. I don’t know what to understand. He is a nice person, and I’m not in love with him. But I don’t mind dating and see how compatible we are. But I don’t want to keep guessing about what he thinks of me. I am DONE reading between the lines and magically trying to understand what guys mean. I improved my communication skills and it’s hard when I am so open about what’s going inside my mind, but the guy is not. I understand that it is a real issue to not be able to articulate, but how can I help him change it and get some clarity about what he feels about me?
