Please help with decreasing my insecurities

Hello!

I feel like I have an extremely case of insecurity.

I want the help but I can’t go to a therapist.

I need help. All I could think of is this app.

I just want my insecurities to go away.

But it’s so hard. I tried reading positive inspirational quotes everyday.

I tried to not be jealous of my husband and his female friend he talks to everyday.

It’s hard not to because the actions my husband has shown me is opposite of what a you would call a person “just a friend”.

I’m tired of snooping through his phone of what conversation they are talking about.

I leave for military training in a couple of months, and we were talking about when I’m gone what are we gonna do for sexual stuff since we won’t be together for a long time. He responded with “well, I’m a man. All men have a tendency to want to fuck everything and everyone.”

That’s when my insecurities went skyrocketed.

I don’t want to feel insecure anymore. I want to able to trust my husband but when he said that, I’m not too sure if it’s my insecurities are to blame or my husband might actually cheat on me during basic training.

Btw, my “why” I’m joining the military is because of my husband and our daughter. He can’t hold a job and we’ve been depending on family members and food stamps for shelter and food.
