Trust issues

I have trust issues in my relationship because of my dad always coming in and out of my life lying to me and being cheated on as well as a cheater . With that being said it's starting to effect me as a person and my current relationship. The being of are relationship I was talking to people that I use too talk too everything but come into physical contact with them and he would didn't like after trying to get me to stop he joined in and I didn't like it so now we committed to just each other .recently he went out of town of town and my only rules were jus tell my where you at ,if your going to sleep tell ,and if I text don't wait 3 hour to reply ...and nd he listened to none one day i texted no answer then he finally repyled and said he was drinking I said with who he read it and no reply then I called him over 20 times and still no answer then he calls # hours later and say he said he lost his phone at his dad's house I do belive him but hard to belive that when he's the type of person who always have there phone on them .I m just confused cuz it's min and hours between message I get people are busy but out of respect for the one your wit it doesn't hurt to I'm busy I'll call you later .
