so my ex and I were in love for about 9 months then split up a few months after he started uni whilst I took a gap year. we broke up because he wanted to focus on uni life. we agreed to stay friends and we talk occasionally but I've noticed recently that he starts a conversation with me and then his replies seem blunt sometimes like he's trying to end the convo. why would he do this? it's been about 8 months since we broke up and I'll be starting at the same uni as him in a few weeks.
