Victoria

So my bf has been deployed for over a month now and yesterday was one of my really bad days. I cried about 10 different times yesterday morning alone. I just had the iud put in a month ago and we both knew it was going to affect my emotions and hormones and man let me tell you it has. From 2 nights ago when he last talked to me after a tiny arguement about something dumb he quit texting me(he is a guy who is on his phone 24/7) so I thought something was wrong I thought he got hurt. I texted him about 3 times that night and then the next morning nothing not even a read message saying he read the texts then I saw that his location was off so I thought oh maybe he let his phone die while he was sleeping okay. So I texted him when you wake up and get your phone charged I would love to talk to you. Thinking we solved our arguement but then he didn’t talk to me the whole day. No explanation why until later that night I was begging him to talk to me. I knew they hadn’t flown anywhere that day because he would of told me the day before if they had to leave the base. But still nothing. So I sat and waited then I had some girlfriends come over and we made cookies cause they knew that this deployment, full time college student, and 2 jobs was kicking me in the ass and it was my first night I had taken off since he left which wasn’t bad. But what made it bad was because the girls came over he called while they were over I thought oh yay I can talk to him and figure out what’s been going on cause something is wrong. I was wrong something was horribly wrong. He had the 1st Lieutenant come in today and the Lieutenant Colonel in which he never told me about so I was freaking out that I did something wrong the entire day so I started calling him later on in the day more to see if I could get him to answer me still nothing then he calls flipping out on me that I was blowing up his phone and was trying to relax with the boys and didn’t want to talk. But that whole day I just needed to talk to him. My family and I haven’t been close like we used to before me moving out so I called my mom to talk to her about how I was feeling and she just told me to rub some dirt in it. I knew it was the iud talking but it was different I had never felt this way before I just wanted to be told that I was loved and wanted on this earth and the people I wanted to hear it from the most wouldn’t even tell me that. So it hurt then I stopped trying to talk to them and I texted my bf can you be nice to me for this one damn day I’m on my period which we both talked about it going to affect me differently with the iud and he called me back and said stop complaining and then hung up and called me back on FaceTime within 2 seconds. I thought it was weird he walked all the way outside to talk to me for 5 minutes before he told me to turn my lights off get into bed because I was tired and he knew it. He just knew and didn’t even have to look at me he said he saw that I had been crying and he felt bad that he couldn’t be there to hold me and he wished he could he was then telling me that when I cry a lot like this it’s cause I’m tired and he proceeded with telling me to turn my lights off and to put my phone up while on FaceTime still but he stayed on and sang to me cause he knows I love it when he sings and then while he was singing I heard him stop and say I want to marry you then he started singing again. I pretended like I was asleep cause I didn’t know if I should say anything or if I should od turned the light on and said what did you say this is me this morning thinking about what he said when he thinks I was asleep I don’t know exactly what to do so I am asking for help on what I should do next...
