Intense or controlling or am I just tired?

I don't know if my boyfriend is too intense , we text everyday and If I don't text him back I feel bad and worry he will get mad if I don't. We send eachother loads of hearts which I don't want to do as much becuase it takes ages and is too much , I just want to send one. Like we say we love eachother so so much and stuff like that and we ramble on but I just wish I could send one kiss and ask how his day was rather than being over dramatic and saying how much I love him. I met him in November and we are going away on holiday for a month I don't know if this is too much or not , we've only been going out for six months. I feel like I can't tell him I'm worried it's going too intense because then he will get upset and say im acting off and then I will feel bad. I just don't want this to be too intense I want to be able to send normal text messages which aren't like a paragraph long. I said I wanted to go out clubbing and he was like we do need to save money for the holiday almost making me feel like I couldn't spend my money on anything else, which again makes me feel bad. I love him dearly and couldn't break up with him but there is certain stuff I wonder if he's being controlling or not? What do you think?
