Do you think i still love my husband?

my husband loves me so much and i can feel the sincerity. he only had one time of relationship with another woman and because i discovered it at once, it ended up soon. unfortunately, i can't forget that betrayal and whenever it pes my mind, we argued so much that it ended up he hitting me. I always forgave him for hurting me because deep within me, i know im not that perfect and i have also my own mistakes not until the time came when he pointed a gun on me. It's the worst thing that i ever had with him to think that he did it in front of our children. i taught its my end. but as usual, i forgive him and he promise not to ever do it again. since then, he never do it again even hurting me a little. my problem is after that incident, i cant forget it even if its more than a year ago. i dont want to have a broken family that's why im sacrificing. i think, my love for my husband has gone and i only consider our children's sake that's why im still living with him. we sleep separately since then because im afraid of him now. but sometimes we make love only to do my duty as a wife but i never feel the same satisfaction as before. can i have some suggestions, opinions to have a peace of mind. thanks to all!
