Good Morning Liza
OK... Here's my .02
An argument of sorts about exchanging "I love you's" with a man you've been dating since April?
Please listen to what he is saying in his responses to you. It sounds to me as if he is not as emotionally involved as you are at this point. I may be wrong, this is just my take on what you have written.
Try to take a little step back... See what happens...
Wishing you nothing but THE BEST.
