Should I try talking to other guys

So I recently joined Plenty of Fish again. It’s a dating site (in case for those that don’t know). So I’ve been talking to this guy for a week. He brought up about us meeting after 1 day of talking. And we both seem to be in the same place in terms of what we’re looking for. We were suppose to meet this past Tuesday because we both had the day off, but I ended up being called into work. He understood and was willing to meet me after I got out of work. Since were I work is at a shopping center, we were going to meet there. I waited but he didn’t show. About 20 minutes after we were suppose to meet he told me he was finishing up some yard work and asked if we could meet a couple hours later. I said no and told him he should have said something sooner. After a couple of hours he texts me and the story changed a little. Apparently he had been doing yard work and his dad fell and he had to take him to the hospital. Now I know he could be actually telling the truth, but I’m so use to being lied to that I told him I had my doubts about what he was saying and that I needed a bit of space and was not up for talking the rest of the night. He apologized and said he understood. The next morning he apologized again and asked if we were ok. I told him I was still thinking. We’ve talked since and I’m giving him one more chance. We made plans for this Tuesday coming up because we both have the day off. Now to me this is his last chance. So if he pulls something like he did the last time, then I’m 100% done. He doesn’t know this is his last chance. So before last Tuesday I did feel a connection but now not so much. I just keep feeling like I’m waiting for the other shoe to drop. So what I’m wondering is if I should try talking to other guys or just wait a little longer to see what happens with this one
