<human>: Give me a shortened version of the text

My BF and I have been living together 1 year, dating 2.5 years. My BF travels weekly for work. That is very hard, because communication dies during the week. I will get one or two text messages from him, and then a daily 20 minute phone call. And that's it. Our phone call is about our days, mostly work.

I don't like him traveling, because it feels like I don't have a relationship during the week (weekends when I see him are totally fine, filled with lots of communication and hand holding and all that good relationship stuff). That disappears during the week. He claims that he is very busy at work; too busy to text. But then I find out that he has plenty of time to go to long lunches with a female coworker. He hears all about her horrible online dates, gets restaurant recommendations from her. He, in his words, banters with her all day long. 

I've been a little jealous of their relationship in the past, but this week it really hit me hard. I haven't been sleeping, which is making these feelings even worse, and I need help understanding if what I am feeling is valid. I am concerned I am no longer important in my BF's life. Work has always been his number one priority. Now he has a coworker that he sees more often than me, who he can talk about work with, who knows the people he works with and can provide her own stories that he understands because he is right there. The jealousy is killing me, and I can't stop crying because of it. 

Is my jealousy valid? What can I do to stop this horrible plunging feeling that I am basically single? I feel like my feelings are both justified and ridiculous. Am I being crazy because I am so tired?
<bot>: traveling boyfriend doesn't have time to communicate with me, but has plenty of time for female coworker. How to handle feelings of extreme jealousy?
