So I have been with my boyfriend for 5 months...but an old crush recently told me he is in love with me HEL?

So the guy that i used to have a crush on is nice and very sweet but i talk to him 24/7 i know he was living with some one and has a kid but he is now seperated...i like my boyfriend alot i love him! What should i do? Should i avoid talking to the other to keep him from saying that he is inlove with me?
