I really need help

Ashley
So this guy I've been seeing for a month is great but I don't know if these are warning signs to look out for..
-he gets an anxiety attack when I don't respond to him.
-he's very clingy (like wanting to hang with me 24/7)
-already said he wants to spend forever with me.
-already said he loves me.
What do I do? Do I break up with him? If so, how? I'm a little nervous..
