Help please

HELP PLEASE....I like this guy but I'm not sure if it's a mutual feeling....like when we are together...I have his undivided attention...he always the one to hold my hand (walking or riding in the car)...like he shows he like me when we are together...(out on dates) but when we are not together...he doesn't call...he texts me (that's all) but I don't feel like it's genuine. He really doesn't say must when he text and he always stop texting me when I'm trying to have a conversation with him. Its been 5 weeks since we've been dating. We may see each other 2-3 times out of a week. He told me he really likes me. Am I overreacting or is it that he does not like me as much???
