<human>: Can you succinctly summarize the text in 1-3 sentences?

Okay, so a month ago I asked out this guy, I'll call him X. He worked at a store that I frequented, so I didn't know much about him going in. We started going out and I've been having a great time with him. After a few dates he told me that he had just gotten out of a long relationship and wasn't looking for anything serious; he just wanted to hang out and have fun. I still have some questions about what exactly that means, but I agreed to it because I'm not exactly looking to get super serious right now either.

However, after our first time sleeping together, things changed. We used to go out several times a week, seeing movies or going to dinner, etc. Now we only see each other once a week at best, and it's just to go to his place and watch a movie/spend the night. I ask to see him more often but he is always busy. We don't text a lot and I feel like I always have to initiate us hanging out. I like him, but not how our relationship is going.

Today I met a great guy (call him Y) while out with friends. He is obviously quite into me, and I'm into him as well. We didn't make any plans or anything, but I heard from a mutual friend that he wants to ask me out. I just don't know how to feel. I mean, I would feel awkward accepting an invitation to go out when I am sleeping with someone else. On the other hand, I am not super happy with my relationship with X, and would like to see where things could go with Y. Plus, X and I haven't talked about whether we are exclusive.

Basically, am I allowed to go out with Y while still seeing X? Obviously I wouldn't string them both along indefinitely, but I would like the chance to get to know Y before making a decision about X. Is that fair?
<bot>: Dating X for one month, not super happy, haven't talked about exclusivity. Want to see where things go with Y. Is this okay or is it deceitful?
