My family says I’m crazy and overreact a lot

Sooo I’m going to give a long story short, I work 3rd 5pm-3am set shift and my bf works 6 days a week rotating shifts from 3rd one week to 2nd the next to 1st and then starting over. This week he’s on 3rd 12am-8am and he’s off Sunday (tomorrow) I’ll give you a little background he’s really close to his oldest sister (understandable) and her 3 kids. He goes over there everyday if not everyday almost everyday. We’ve been dating 1 year and 3 months and we may have moved a little fast so I’m used to always being with him. We both just started our jobs ( he’s been at his 1 month since dec. 3rd I started mine dec. 26th) he was on first for 2 weeks through training and had the week of Christmas off now this is his first week rotating and he’s on 3rd. All throughout the week I would wake up around 1pm and go sit with him at his house from about 2:30-3 ish pm to 4:20 pm cause I go in at 5 pm. So today (Saturday) is my first day off and he comes over from his sisters house around 1 or 2 (I can’t remember because I’m aggravated) but he just left at 4 saying he’s going back to his sisters. I was like ok I understand he’s family oriented but next week when he’s on 2nd I’ll hardly see him cause it’ll be from 4pm-12pm so I’m trying to spend as much time as I can with him. Sometimes I feel as though I may be overreacting with him but then again sometimes I feel like he’s dating his family and not me like I have to fight for him. Or maybe I just need to live life one day at a time, I just don’t want to waste my time it’s precious. (Btw we don’t live together we both still live with our parents) also all opinions are welcome
