My girlfriend has major trust issues but have I made her this way?

I’m a dude. Don’t ask why I’ve made a women’s account I just found this website it was for this question cause I don’t wanna talk to anyone about it.

my girlfriend is 21 and I’m 27. So I guess a big difference. I will put my hand on my heart and admit I have cheated on her. But this was back a long time ago when I wasn’t sure and just majorly f’d up I say sorry everyday.

I have a job with my buddy we both work together and do nights till around 3am. Me and my girlfriend live together. The job I do with my buddy is close to his house about 2 minutes away. I get so tired after work and want a bit of beer and PlayStation so I sometimes sleep at my friends house since we work together, my girlfriend hates this and automatically assumes I’m cheating on her when I don’t come home. She says she feels insecure. I guess we don’t do much together but it’s because I’m working so much?

I love her. She’s beautiful, patient and kind but damn she’s so insecure and has a go at me most days for not coming back or she says I’m cheating on her and tried to unlock my phone. Is this my fault or is she just crazy insecure how do I help her
