Not sure what to think, is he sincere?

He told me he loves me but he was drinking and when I didn’t respond right away he said it again. Actuality he said it 3 times. I do love him. I’m just not sure that’s how he really feels. He keeps his emotions in most of the time and very guarded. He’s been hurt and he’s told me about it and his insecurities. It’s hard for him to trust. What are your thoughts about a guy saying he loves you while drinking?
