If my boyfriend moved in February this year and already is moving out this July, is this him trying to break up?

He moved in February, I thought things were okay between us. I have felt distance grow between us but he just said he was swamped at work (he’s a lawyer). Lately I’ve noticed he makes plans on weekends with his friends more and he seems off. Recently he told me he was looking at apartments and found one and has decided to move out end of the month just because he thinks we moved in too fast together but told me it isn’t a break up. But he seems way colder than normal, should I be concerned?
