I love you

Lately My bf and I have been going through a lot of ups and downs but we always get through them. But our thing is whenever we get off the phone or even when we are leaving somewhere or whatever it may be we always tell each other "I love you" it's something we've done since the beginning of our relationship years ago. However as of late because of recent circumstances and issues and arguments he hesitates to say I love you or sometime she doesn't say it all. And it hurts and I tell him and he pushes me away or just keeps trynna blame it on me so because now i feel like he's trynna force it and I wouldn't want that of him and Idk what to do ladies.
