Search Results: thinks i''m lying

First off... me and my boyfriend been togeth for over a year
I had a bad previous relationship which ended 3 years ago
But i still have some trust issues
So i dont fully 100% trust my boyfriend
Over the course of our relationship, he has given me his passwords to his devices (phone, computer, etc)
I was checking his phone the other day and he was searching up girls on his fb and instagram (girls that he knows.. from work, from his high school, from primary school)
But he doesn't talk to any girls.. only the ladies at his workplace (he works in nursing home so majority working are old nurses and middle aged nurses but there are few young girls too)
Im not sure why he did this?
But i was quite jealous and got abit mad so i confronted him about it
Our conversation:
Me - so i know you're talking and searching up girls?
Him - yeh i talk to girls from work only and its all work related
Me - why u searching girls up? I saw your fb and instagram
Him - i dont just search girls up. I search guys up too. Wth?
Me - so u wanna be with those girls u searched up?
Him - what u talking about? I cbf talking about this. I did nothing wrong. Think whatever u want babe.
Me - yeah you're searching up and looking at their photos and all that
Him - think whatever you want. Im not doing anything wrong. I know im not doing anything wrong. I know what i do. Im not cheating on you. You even know all my passwords. Stop being insecure. Are u trying to argue with me like u always do? I can't be bothered arguing right now.
Me - and you liking and commenting girls pictures (*im lying about this by the way.. just wanna see reaction*)
Him - um no i dont. I know if i do, you will go psycho on me like u did before. And i had to spend hours to calm you down. Yea dont have time for that shit so not going to do it.
He was talking to me throughout in a calm tone
Wtf?
Does he seem genuine about it?

Me and my boyfriend was talking last night over the phone about how he hates his job (of 8 years) and wants to try to apply for policing next year
He has told me this goal of being a police before we even started dating
So anyway this is our conversation:
Him - im definitely going to apply for police next year
Me - oh okay nice
Him - yeah. I know i have to do a course first and then have to go to the academy school which is 2 hour drive from where we are
Me - how long does the academy go for?
Him - i dont know.. maybe 4 or 5 months.. gotta check
Me - so i can't see you for 4 or 5 months?
Him - i think we can take weekends off so i can come drive down to see you and all on the weekends.. but does it matter if we dont see each other for 5 months?
Me - ofcourse it matters! Its hard not seeing your partner for 5 months!
Him - but we can communicate everyday?
Me - but you're gonna be staying there.. there's other girls around you
Him - babe.. im going to be focusing on this. Not other girls. Im serious about being a police. And im serious about you.. look im going to tell you.. just dont get your hopes up though.. but if i make it and become a police, thats it.. Im going to ask your parents for your hand in marriage. I would marry you. And anyway if your parents know im a cop now, they will feel more secure.
Me - wait.. wtf?
Him - yes im serious. If i get into cop, my life is complete. I will be settled. I will be ready to get married. So please stick with me. Dont leave me.
So guys, should i be worried about all of this?
Do you think its possible he could be lying about marrying part?
Im just scared that if i can't see him for 5 months and there's girls in the academy, then he's gonna lose interest in me... or we both gonna lose interest
I dont wanna stop him from his dreams and goals though..
He has told me that as soon as he's settled, he would be thinking of marriage and kids later
We been together for over 1 year
But i dont know what to do or think about it all😔😔
by the way im 22, he's 27
