Okay so I can’t believe this happened!

So my friend got into my ex’s snap chat, don’t ask how she is just a hacker😂 my ex told me he wants to get back together but I remember beforehand he said that he has a friend that likes him and he admitted that he kinda had feelings but didn’t want to ruin the friendship. My friend read their messages and before he told me he wanted to get back together he had messaged her saying stuff like “you’re an amazing person and I think you would be a great girlfriend, but I don’t want to mess up our friendship and I don’t really want to get into anything right now” and “I think you maybe would be a great girlfriend in the future tho”. And then she was all like “I’ll be here waiting”. So I felt like he was letting her down easy but idk. He also then kept texting her over the next two days, same as when him and I were texting. It was just friendly conversation and he says he wants to be with me, but, should I be worried? It just seems off kinda.
