I need some serious help

I have been with my boyfriend for 15 months now. I want to break up with him but I don’t want to hurt him. I feel like I have fallen out of love with him while he still thinks everything is totally fine.

He is very shy and I know that so I cut him some slack - lots of slack. (Probably too much.) I text him almost everyday and say something like “hey” or “what’s up” or “how are you doing”. The part that bothers me is he reads it and chooses not to reply. He ignores me. It honestly has been over 2 months since we have actually talked to each other.

I feel really bad because I am getting really hurt by this but he acts like everything is fine. I don’t think he even realizes what he is even doing. I also have three guys that have been telling me I’m beautiful and smart and kind. I really want to break up with him but I am scared I will hurt him. Also my family is like in love with him and everyone tells me he is a good boy and he’s a keeper but I just can’t take being ignored by someone who is supposed to be there for me throughout everything or at least some things. So what should I do? I need advice!
