Help!!!

Iv been married for 18months, we had the greatest relationship. Problem is I keep finding him chatting to other women. He doesn't meet them to anything but messages are explicit and pictures exchanged. He has he has a sickness and he's sorry. He will give it up. He needs to give up for himself not me he says. We are God fearing people and he says he needs to fear God and stop this. I'm so fed up of him doing this to me. I'm 19weeks pregnant with his little girl. We have wanted a baby so bad. He says he will change this time. I'm from the uk he's from North Africa. I moved out here, I left everything and came here for him. Well I have decided to give him another go but I can't get over what he has done to me. I read explicit messages and saw naked pictures and even him describing what he does to me his wife. He says he loves me so much he's made mistakes and he will change. I want to believe him. I so paranoid when he's on the fone to anyone and I'm even more paranoid when he leaves the house. I feel he is downloading FB and chatting to women again. But He's really making an effort, calling me all day, messaging me telling me he loves me and I'm beautiful. Iv started having nightmares and having panic attacks at night he's there for me and he's sorry for everything. I don't know how to trust him again? Can anyone help? Anyone been in this situation? How did they trust him again? I want him to get rid of his smart fone for now and just have a normal fone for now until I can trust him again but I know he won't do that. But he does turn the wifi and 3G off from his fone when he now comes home and is not on his fone at all when home. I love him for the sake of God and want to make this marriage work I don't want my little girl to grow up without her daddy. I'm returning back to the uk in a coupla weeks to give birth there but he is working on his visa and will follow later, I'm so paranoid now when he goes out, what am I gonna be like when we are long distance from each other. I don't know how to trust him again? Has anyone been in a situation where they have been cheated on and they have forgiven and forgotten. Iv forgiven but I'm having problems forgetting. Please advise me on how to trust him again. I'm a mess right now emotional and pregnant and helplessly in love with my hubby who I know is a good man deep down he just has this sickness in his heart. We don't have any form of counselling in this country I don't know what to do? 😢😢😢😢😢
