This is not a very clear cut problem and I would really appreciate some help.

I was talking to my now boyfriend for about a year before we eventually met up. The reason for this long frame of time was because I was very ill and was in and out of hospital - which he was aware of - and it was clear I was not lying about this as my health problems had impacted massively on my university exams and I was made to sit them later. 

When we first started talking, he would drunkenly text/snapchat me and it was clear that he was doing this with multiple other girls. About 8 months before we met up, he told me that he liked me and he wasn't hooking up with anyone else - completely off his own back, I knew I wouldn't be able to commit to seeing him so made sure I was not the first to say this but told him I reciprocated. 

When we finally met up, we decided instantly that we wanted to be exclusive and during the 6 months we have been together there have been no problems whatsoever. However, when I have asked him about the other girls he was sexting etc, numerous red flags started to appear. 

So 6 months down the line and after countless conversations and lies it appears he slept with two other girls, was sexting a handful of others, 3 of which he had previously slept with - and he had been in contact with these girls up until the weekend we met. I have no problem that this happened, as I was pretty aware these things were going on, I just feel that it's hard to trust him. In our most recent conversation he admitted that he probably would have slept with one of the girls he was in contact with if we hadn't of met up when we eventually did. He has a long history of cheating and it's taken 6 months and a lot of questions by me and lying on his part to get where we are now. Any help with how to overcome this?

Boyfriend slept and sexted multiple girls before we became official, problem is not that it happened but that he has lied so much about it the trust is shaky
