My dad and others say my new boyfriend is taking advantage of me….

So I’ve been dating this guy for five month and I’m in love. Some people say love is blind which is true but we’re not blind.
My dad doesn’t like my boyfriend at all. I mean he was okay with him until two months ago.
He kept saying he sees a lot of red flags. He said we haven’t gone on dates in two months and he doesn’t seem happy with me anymore. He overheard that he’s been seeing other girls behind my back and he hasn’t shown love to me. He said he I should have chosen my guy (let’s call him Eddy) friend since he truly likes me.
I didn’t want to hear it and I asked my sister about it and she said dad has a point I better listen to him.
I know my boyfriend and I haven’t gone on dates or hung out in two months, he hasn’t called me back in three months. What a way to start the new year! I called and text him but I figured he was busy with work. My sister said, “Wake up! He is using you as an ATM, he doesn’t respond or respect you as a person and honestly he’s way out of your league.”
I scolded my sister to not talk trash about my brother and she said, “No you needed to hear it! I can’t believe you’re this naive. He doesn’t love you! He doesn’t care for you like Eddy does. Quite frankly, Eddy is a better man than your loser boyfriend.”
Eddy is my friend and I only see him that way.
I finally get happy and my dad, siblings and whoever don’t like him.
