We haven't had sex in over a month.

My fiance and I haven't had sex in 5 weeks. I know because I track my irregular periods and sex in case of pregnancy. Anyway it is affecting me.. We already don't have a great sex life. On good weeks we have sex once a week. Half the time it happens every 2 weeks. We've been together for a good few years. But lately he doesn't care for it. After the first couple weeks I'd grab him sexually. But he'd just shrug it off. It's gotten to the point where I'm just bitter about it. I don't even want it anymore. I don't want him to touch me. It's got me thinking maybe there is someone else. We don't get a long super well lately anyway. He is always pissed and angry. We butt heads a lot. We've been very distant from each other. I'm so sexually frustrated I've been considering certain things in complete transparency. I don't like this. I don't like us right now. I am sexually frustrated but also frustrated with him. It's a weird situation. I just wanted to vent.
