HOUSE OF DARAM: Chronicles of BV

I am dating this guy that loves and respect me so much. We met some time last year and kicked off a relationship January this year. He is 34years. My problem is he cheats. I was at his place a couple of weekends ago and out of curiosity I checked his phone ( something I don’t do before) only for me to see his numerous chats with different girls. I asked him about it and you know the usual lies. He apologized. I am currently on leave at work and at his place presently because we are both preparing for a professional exam ( he funded it for me) and I checked his phone again only for me to see that he actually had a girl at his place through out last weekend. I have promised myself I won’t raise the issue with him again because men hate women that nag and are turned off by women that check their phones in their absence. This man has been extremely nice to me. Where I work he got it for me, I am currently running a professional course all thanks to his assistance, he is working on me getting a federal government job through his connection.
HOUSE OF DARAM: A heart touching story
This is only but to mention a few of all the love he showers on me. I give him everything he wants in return ( sex, good food, attention, affection). What answer do I give him if he finally proposes to me?. Yes I love him but can I actually stand sharing my man with other women?, or should I just take a walk? These are questions I am asking myself. I am going to be 28 years next month. WHAT DO I DO??
