Dating new person

I’m dating someone new and I keep finding myself feeling really disappointed and sad when he doesn’t make plans to see me. I brought him a bday present earlier and he seemed like he wanted me to leave. Sometimes he is very affectionate but there are times when I can’t tell if he likes me.
C: didn’t want to hangout with me earlier
T: I like him more than he likes me
F: sad and disappointed
A: withdraw and wait for him to text me or make plans
R: don’t spend time together

When I date it often feels like I’m on a roller coaster. I want to not feel so disappointed when things aren’t exactly how I want. What would some useful thoughts be in this situation?
