Search Results: signs a guy is in love

We work a later afternoon shift and after work he invites me to come over every night. We sit and talk for hours sometimes having sex after sometimes we just part ways and make plans to see each other the next night. For months he was forced to work one day every weekend till about 7 pm. On the weekdays we work till 11 and sometimes hangout till 5 am.
We had some time off over Christmas but he got caught up in family stuff and then was sick so he ended up cancelling on me multiple times. He does that a lot. It seems like unless I'm driving to his place I won't be seeing him. He asked me if I'd want to go on a holiday with him. He planned a double date for 3 weeks from now.
I asked him once 'what we were' and he said we're basically dating but I want the date that our relationship starts to have a cute memory attached to it.
I've told him multiple times that I need to have actual dates with him not just see him in the middle of the night!!! All we can do is sit in his vehicle because he lives with his parents who don't want me in his room at 2am. When I was telling him to stop cancelling on me and that it felt like he was always making excuses he said I <3 you (I think it was just to get me to stop asking him questions).
The other day he told me he sees this as a long term thing. He wants to take it slow and make it last long. Later I said I love you to him and he just kissed me and said I was cute.

After all that my question is: Is he really too busy to see me during the day? Does it seem like he's all talk but when it comes to actually living up to his promises (our plans) he never follows through?
