<human>: Can you give me a shortened version of the text?

My family goes on a trip to our beach house every summer and a few months back I talked to my friend Ashley about her wanting to come with. She was excited. I didn't make any promises and we definitely didn't make any plans. About a month ago I started dating my boyfriend, Thomas. He would be thrilled to go on the beach trip because he loves the outdoors and that kind of thing. I have not asked him if he wants to come but I'm sure he would, and I would love to have him come. Ashley recently asked again about the beach trip and I told her that it may not even be happening because of being busy with work this summer (which is true). I also was gushing to her about Thomas and I suggested that she meet him and we all hang out this summer, and then she revealed to me that she used to hook up with him, and would not want to see him because that would be awkward. I recently found out that the beach trip is in fact a possibility and there's a time we could go. I really want to bring Thomas, but am I obligated to bring Ashley instead? I would bring them both but I think that might make for a really awkward weekend.
<bot>: Talked about a trip with friend before I started dating boyfriend. Now I want to bring boyfriend but I can't bring them both. Am I obligated to bring friend since I technically invited her first?
