<human>: Can you summarize the given text in a few sentences?

So my boyfriend and I recently got back together after being broken up for a few months. It's not the first time he's broken up with me. 

My boyfriend also never tried to contact me during this breakup period, so I took it as official and started seeing new people.

I met guys off dating apps and went out with and slept with a few of them over a period of a few months (One after another. Never going out with two people at one time) but there seemed to be a lack of chemistry. 

My boyfriend recently apologised and I took him back. A part of me feels like I should I tell him about the few people I dated and slept with but a part of me feels like telling him will ruin whatever peace we now have. 

Is it better to start a fresh and leave the past where it lies?
<bot>: Broke up - then got back together with my SO after a few months, do i need to tell him about sleeping with someone during the break up period?
