Sick of fighting

I’m engaged to a great guy but these past few months have been rough yesterday he said he was always wasting his time with me and today I was stressed about work and looking for my name badge and he said I needed to stop being bipolar I don’t know what to do i am very clingy I like texting him while we are at work and I like hanging out with him but he says it’s too much but it’s just me being me I don’t want to break up but I don’t know how much longer I can do this
