I have been on two dates with this guy. I am 24 and he is 28. We went on two dates around a month ago. Both of the dates went well. On the second date, he talked about meeting up again and going away for the weekend. I found it a little odd that he would want to go on a trip away so soon after meeting. I told him that I would rather go on a few more dates first. He said that was fine. I asked if he wanted to meet for a third date the following week. He said he would, but he was ill. He was ill for the next two weeks. Then, he messaged me saying he was feeling better. I asked if he wanted to meet up for a third date again. He said he would, but right now he is on holiday in a foreign country. I feel as if he is not really on holiday but is stringing me along as it is quite difficult to travel now due to covid restrictions. He said when he comes back from holiday, we can go on the trip away. I asked if he wanted to meet for drinks again on 23rd December when he is back from holiday, and he said he might be able to. Two days ago I messaged saying it would be good to meet for drinks on 23rd December, and since that he has not replied. I am very confused. I am not sure whether he is really interested or not. I am worried he could be stringing me along until he meets someone else. It has been a month since I last saw him. What should I do?
