I (33 f) and my boyfriend (35 m) have been together for seven months now. He is a really good guy that sometimes has a hard time communicating his feelings. However, sometimes this lack of communication can make me feel anxious. Sometimes he wont text me all day when I have texted him a couple of times during the day, and then he will call me and act like he didn't practically ignore me all day. This is becoming more and more frequent. I have a lot of insecurities centered around jealousy and cheating because of my ex's. My boyfriend knows this and it has caused some arguments in our relationship because he said that it is not his job to reassure me with my insecurities. He has also said to me "I don't have time to cheat". After our last big fight concerning this where I ended up crying, he called me the next day to suggest that we go to counseling so that he can better support me as my partner with my insecurities. I agreed and we moved on. However, this is where I might be the asshole; After a day of him ignoring my texts and him calling me to talk, he casually brought up that his work friend said that he should volunteer for a work trip that she is going on in a couple of months. For context, this work friend and him carpool to work meetings together at least once a month and they talk to each other on the phone about work related things a lot. She is his mentor. He says that she is his work best friend and that she is his friend outside of work too. He said that she said this would help his career, and he got defensive when I started asking more about it. Immediately, alarm bells went off in my head. I thought about all of those stories where people cheat on their partner on work trips, so all I could said was "Ok" and "How long will you be gone?". He told me that he doesn't know how long it will be but that it's out of state. He told me that its not for awhile, like that would make it all better. A little longer into the conversation, he said that he had to call me back and he hung up without saying "I love you" which he has also been doing more frequently. When I have brought it up in the past, he said that I was being clingy. When he hung up, I felt extremely hurt and anxious that he didn't even think about turning down the volunteering opportunity. I feel like he should have thought about at least saying no because he is in a relationship, but he didn't. He immediately said yes and basically just brought it up to at least tell me. Im worried about him going on the trip because of all those stories and because he would have time to . . . You know. We have been together for seven months, but he just brought up counseling because of my insecurities, and now he wants to go on a work trip with another woman. So AITA for getting upset? P.S.: A lot of the time, he tells me that he doesn't like clingy partners, but he is clingy himself a lot. One time, I didn't text him back when I was sick, and he broke up with me because he thought I was ignoring him. When I explained to him why I didn't answer, he acted like he never broke up with me. He tells me that he doesn't like jealousy, but he got jealous over a delivery guy because the delivery guy smiled at me. Also, when I worked a more demanding job, I couldn't text back as much, and he texted me, "I don't think this is working. I don't think I'm a priority to you." I agreed and said we should just be friends. He basically had an "Oh shit" moment and tried to get me back for a whole week. He was texting me at least six times a day.
