Haven’t had sex in so long

So I’m kinda at my wits end. My boyfriend and I live together and have been together almost 3 years I love him so much but I feel so alone in our relationship I kinda feel unwanted at times we haven’t had any type of intimacy in almost a month. There has been several times when I have brought this up to him and try to explain my feelings to him but it’s like it does nothing he doesn’t really say anything back when I’m trying to have a serious conversation with him and there was one time I said aren’t you going to say anything and his reply was I don’t want to say anything and start an argument.? We hardly ever fight so for him to say that through me off it’s like he’s afraid of what my reaction will be idk. I just can’t stand constantly being rejected when I try to initiate things and he tells me I just pick the wrong times to do that. Yet I try in the mornings afternoons and night so don’t fing tell me I do it at the wrong times.

Not sure what to do I’m just done feeling like this.
