Advice, what should I do ? I just want things right again.. Is it too much to ask for?😒

So February 1st me and my boyfriend got into this fight.. We hasn't seen each other like we used to and he doesn't text me back or anything. Of course it hurts my feelings cause I been with him for 3 years. Well he came and gave me roses & chocolate for Valentine's Day.. But we didn't kiss or hug. Just walked away. Told me he'd talk to me later .. But there wasn't an later. He stays out to 3-4 in the morning riding around.. Told me that if there was someone else he wouldn't have brought me anything. But what hurts the most is that I'm so scared that I could loose him.
